Yes, indeed. In theory though reftables could also be the solution to
the underlying issue: the client can be tought to read the "tables.list"
file and then fetch all tables listed therein. The result would be fully
consistent, unless any of the tables gets garbage collected. The client
would notice and abort the operation, after which it could restart the
operation.

In that case there would be no need for git-update-server-info(1)
anymore. The "tables.list" file sits in a well-known location,
identifies all other tables we have to download, and there are no
atomicity issues anymore.

The catch of course is that somebody would have to implement this :)
