That’s probably it. If I only had one 26er, I’d definitely keep it geared. As I have a few though, I’m definitely tempted by the idea to try one fixed but the fact that 26inch wheels with fixed compatible hubs aren’t readily available is a bit of a hurdle and I’m not quite sure whether it’s worth the effort.

26inch wheels with fixed compatible hubs aren’t readily available
A Walker brother is still doing Fixxer clones to order. There must be millions of 26" MTB wheels out there with compatible Shimano freehubs.
If you don't mind losing the rear brake (or you already have rim brakes), a 135mm 6-bolt disc hub flipped over with a 6-bolt sprocket aligns reasonably well with the middle ring of the MTB triple crank found on most of these old bikes.
I feel like so many of these retro MTBs are being built up as comfy townies, tourers and budget gravel bikes, so few people would probably be bothered of building/finding a suitable rear wheel. Also most will have decent and versatile gears, brakes, etc
