Actually I know only 2 (3 if we count AmiArcadia) worthwhile ReAction-progs:

- AWeb ..... well pretty obsolete eversince the 1st beta of Sputnik

- ZoneExplorer ? That fractal-thingi from a few years back, maybe nice, never tried.

I won't even consider infecting my systems with this ClassAct/ReAction-crap for any of the above.

Your argument might (and yes only might) be true for someone still running an 030 based Amiga, but for everyone else it will be impossible to tell the difference.

You say that MUI is 3rd party and has to be extra-installed, but I doubt you'll find many Amiga-users that don't have it installed (except maybe for those that only use it for running WHDLoad-slaves).

Dunno how much work it would be to rewrite (and to be honest I can't say I care much).
