Well, in the past I attempted to land a "local" file system type that
could be used for file systems that were available via docker (and so
there was no block device to mount and unmount).  This was useful for
testing gVisor[1] and could also be used for testing Windows Subsystem
for Linux v1.  As I recall, either Dave or Cristoph objected, even
though the diffstat was +73, -4 lines in common/rc.

So if it is really simple, it's also not hard to keep it in an
out-of-tree patch.  I've been maintaining [2] in my personal xfstests
branch, and kept it rebased on top of next, for years.  I figured it
was easier to keep it out of tree than to try to fight through Dave or
Cristoph's objects to get it upstream....

So even if we can't get Lustre support upstream, I'm happy to maintain
it at my xfstests tree on github, much like I have with the "local"
file system type, for the past 8+ years.
