Adding in my two cents about the whole "will Sirfetch'd be able to use Stick" debate... I think it will. My reasoning? Well it's based on how they handled other Pokemon-specific held items:
Clamperl's Deep Sea Scale & Deep Sea Tooth: The fact they give Clamperl any kind of boost is a bonus to their true purpose: being used to evolve Clamperl. They might as well be as useless as the Sachet & Whipped Dream.
Pikachu's Light Ball: Mascot status. Without it there's no reason not to evolve Pikachu into a Raichu. With it Pikachu's Attack & Special Attack are higher then Raichu's and has no drawbacks unlike Life Orb & Choice Items or only gives a small boost to one stat (Muscle Band & Wise Glasses) or for a Type.
Chansey's Lucky Punch: As mentioned, it's a joke on Chansey's name (specifically its Japanese name which is literally "Lucky"). If Lucky is lucky, its Lucky Punch will let it do a critical hit.
Cubone Family's Thick Club: The only one of these items which affect multiple Pokemon, it was even extended to Alolan Marowak. Why? Well could be because they all wield femur bones as weapons and the Thick Club is just a femur bone that's assumably more sturdy than their normal one. Also the length of the bone doesn't seem to be an issue, Cubone, Marowak, and Alolan Marowak's clubs are all different lengths but either the Thick Club either is the perfect length it's usable by all or it can somehow change shape depending which Pokemon is wielding it.
So, where does that leave Stick? Stick probably won't be needed to evolve Farfetch'd, Fafetch'd isn't a mascot of anything, and there's no joke connected with Farfetch'd and Stick. So Stick falls into the category of the Thick Club. Now, yes, there is a massive size difference between the leek that Farfetch'd and Sirfecth'd uses. But the thing is I would buy it if you told me that the Stick simply grows to match the preference of Farfetch'd or Sirfetch'd because it's still a plant even if it has been cut.
(Though honestly I think these items really need an update to make their effects more useful, maybe even have an effect for Pokemon who aren't the target species. This also goes for the evolution items with no in-battle effect, the normal held items which are needed to evolve certain Pokemon, and the Incenses)
It'd be lazy if they went with Gen 4 remakes at this point because we already got Yellow remakes on the Switch with Pokemon Let's Go Pikachu and Eevee. That'd make three main-series releases on the Switch with only one of those (SwSh) being an original idea. That's subpar, in my opinion.
Remakes and remasters just need to stop already. They've been popping up everywhere since the start of the decade, and all of this nostalgia-bait is now affecting the film industry, too. I accepted FR/LG and HG/SS considering RBY and GSC had no connection to the GBA and beyond titles, but ORAS and LGPE were completely unnecessary, and DPP remakes will be just as unneeded. If this continues, we'll be seeing Sun and Moon remakes several years into the future, taking development time and resources away from original titles.
At this point the Let's Go games are being treated as their own thing. It's "connected" to the main series but it's not part of the "core series" unlike the remakes as we know them.
As for them stopping the remakes, I agree and disagree. I agree that we kind of don't really need to play through the same story again except with the updated graphics and mechanics. BUT I disagree because I would then rather they tell a new story in the old regions that maybe takes place a year or few after the original games. I played DPPt, now show me what happened after them.
