That would mean writing a lots of itsy bitsy files (i.e., using the file
system as the DB) if this is going to have any kind of meaningful
concurrency.  Otherwise Emacsen will just be overwriting each other's
data aggressively.

And it'll be dog slow.

So I don't see the use case.  Virtually all systems have sqlite, and if
the users have chosen to not build Emacs with it, they don't get the
persistence feature.  That's no different from when they choose to build
without libxml -- they don't get to read web pages in Emacs.
