Combining/sharing the blob-store and the metadata that defines it is
the biggest one. But we could potentially share all data about the
BASE tree. If the same node <uuid, path, rev> occurs in multiple
working copies, then information about the text and props can be
I believe and agree with you that there is little benefit in putting
all the WORKING trees into one database, beyond the small advantage of
opening a single database.
