fvwm95 was a fork of fvwm2 and has remained in that state, and never updated.
It was created at a time when the theming in fvwm was not as flexible, but it's completely possible to emulate all of fvwm95 in fvwm3, and behind the scenes, the application support in fvwm3 greatly outweighs the version of fvwm2 which fvwm95 wad forked from.
In other words, it remains a curio in fvwm's history, and that's where it should remain.
