I really don't think that's wise -- there's more to filesystem choice than
stability and efficiency.  For example, at one stage I maintained an
actively-used partition formatted as fat32, despite its lousy performance
in linux -- because it was shareable between Win32 and linux when
dual-booting. Reducing filesystem choice has many side-effects.

PS: if I recall correctly, Reiserfs did have an issue at one stage where
it was liable to data loss.  In 2001/2002 (this may have been fixed since
then), Reiserfs wasn't a true journalled filesystem -- metadata was
journalled, but file contents were not.  I haven't experienced it myself,
but I've heard reports of corruption and data loss due to this.
