The downside is that it no longer picks up updates, fixes etc. from the
official upstream support for libext2fs / libreiserfs, so we're just
duplicating the places where filesystem support needs to be maintained.

If xen packages are properly built, filesystems will Just Work anyway.

That I can agree with.  But I'd rather see that API done as a wrapper
around existing upstream filesystem libraries, rather than forking fs
userspace support entirely.
