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. :-)
