This. Keeping your retired oldie on is fine as long as the horse is happy and comfortable, but IME so many are not. Folk declare that they won't give their arthritic old nag bute or Danilon due to the peceived side effects, and instead give some untested herbal fluff and the horse hobbles on. I'm close to making the call for my senior Cushing's mare, tbh she's more useful to me alive than dead as she is a good companion but her needs must come first.There are also far too many lame horses limping around fields retired often owned by those who attempt to take the moral high ground in this debate with serious stuff wrong with them many being kept on no medication for pain this is IMO just plain wrong and I find it impossible to understand their reasoning .
I do agree that to ponies age is more a number than with horses, so they can still be in full work in their 20s. We once took on a 36 year old 12hh from a rescue for light leadrein work and as a companion, and he was grand. We let him go 6 years later, still sound and perky but getting very thin despite getting 5 feeds a day. Swizzle pictured age 40 (it cost a fortune in feed to keep him looking that good!).
