Not specifically, no.  From the description (not having read the
patch) I was somewhat concerned that it might affect something
outside that narrow use case.  If that's not possible, then I'm more
comfortable putting it in a release that soon after it hits the
repository.
It's a judgment call, and you're clearly in the best position to
make it.  You asked for thoughts, so I shared my concerns.  :-)
