I think part of the reason apps like Photoshop and Word got bloated is that their audience got watered down and are fairly mainstream software.

I'm sure there's a lot of old niche software that feels modern and unbloated. Nuke[1] is 31 years old and Houdini[2] is 27. Maya[3] is 26 years old. I would say Maya feels bloated--but at larger places I've worked, people have avoided the newer viewports with more features because the "legacy" viewports are so fast.

It may be hard to make it feel "modern," but I love how optimized "old" code can be if they've been able to resist rewriting it.
