There's some that never took how fast moore's law went through 94-02 so all the advancements assumed to be a trivial blur there. STB 3dfx's marketing scheme doesn't help assumptions, as well as the cult status coming off that (enough to fall for fake 3dfx companies). Voodoo3 emulation entitlement was already assumed to be an 'easy' iteration of the Voodoo2 and no one was asking about the Banshee...
(personally much much much prefer other 1st gen 3d (rage, msi, rend) before any v4/v5/tnt/pvr/etc. I was never interested in Voodoo4/5 in the day, and it wouldn't really bring more games to play that a V3 couldn't anyhow)
There's also the whole apathy on giving back in the whole 'open source movement' in the past decade coming from a bunch of different factors and that's affected many, many different smaller projects that are not overly established on PR and/or funding. Like even with the recent displeasure of GTA remasters lately, OpenRW is relatively unknown in the hubbub over source ports as that's a years ongoing project that doesn't play every GTA3 game perfectly yet as it's not a decompilation, and there's many that believe nethack is dead, etc. not to mention the "free speech" license's own various social problems.
