I don't think so. The right fix is for the slave to proxy over to the
master for reads as well, when a client requests a revision higher
than the slave's current youngest.
An alternative (for less load on the slave) is for the client to
notice the particular error from the slave, and contact the master
itself. But that might have working copy metadata implications.
I don't think that...

... solving this for 1.5.0 is realistic, though would love to be
proven wrong of course.

Huh, yeah, that sounds like a separate bug, but still a bug.
Thanks for not forgetting about these issues!
