It's an inherent limitation in how Mercurial has done discovery for ages
and AFAIK has nothing to do with filtered changesets. If you found a
bug, it was by coincidence :) Mozilla's specific problem could be
remedied if we increased limits on our HTTP servers: Mozilla is
footgunning ourselves. But there *is* room for discovery to be more
intelligent. I previously tried to start a conversation about it [1],
but it didn't seem to go much of anywhere.
