Of course, the basic premise for this feature is "let's assume that our
file and/or operating system suck at providing file system functionality
at file name granularity". There have been two historically approaches
to that problem that are not independent: a) use Linux b) kick Linus.
Option b) has been fairly successful over quite a bit of time, but at
the current point of time, it has become harder to aim that kick on a
single person and/or where it counts.
The database approach is an alternative approach based on kicking an
alternate set of people, namely database rather than operating system
providers, based on the assumption that the former have softer behinds
(the backend-based approach) making them more sensitive to kicking.
So the database approach is most promising on the "what are we going to
do if our operating system vendor won't bother with sensible file system
performance" angle. Which isn't doing total system architecture a
