yep
by other side, its work is excelent, in fact reiserfs (v3) is the best filesystem that i EVER used, I never lost any file in many crashes with it (instead, all ext* filesystems was not so reliable and gave problems or lost files), unfortunately this is true only up to the version 3.0 of elive, newer versions has reiserfs unstable (kernel developers started to use VFS code that made it somewhat buggy, and aparently is not resolved yet because very few people uses reiserfs... SO BAD! since its a so good filesystem...)
so unfortunately, is almost not maintained, not updated with new features (discard, ssd, etc... new features), etc
by other side, we have reiser4 and even reiser5, which is an entirely redesign of reiserfs, it is surely an amazing good filesystem but unfortunately because of the author's reputation (but is since years maintained and developed by a different person), is almost not used by anyone and also not included in the kernel tree... this means that unfortunately it has a few bugs that can makes it not a so good option for production, if we want to have it in production (because is a very good filesystem, just read the wikipedia details of it 
) we need more testers / reporters, etc..
there's a funny photo of him (or a fake one) being arrester for car driving... yeah he maybe was not arrested, but just because has so many money, with a big list of opportunities to have been arrested lol Microsoft litigation - Wikipedia
yeah! 
I always go back to e16 to work more stable when newer E's was not enough stable 
in fact e16 was selected also because of that reason: to focus on the development while using a stable desktop (which surprisingly, the actual result is really good even today's!)
you couldn't make the desktop crash 
they will be even better after the next version of eltrans which will enforce a good proofreaded english
