Just a quick comment on the situation: I was the one that filed a bug with RedHat. In turn that was based on a bug that had been previously fixed in Python that resulted in it not parsing valid regex. My understanding of what was happening and the fix would be that it's unlikely to break something, just fix the particular case.

From my perspective, if this regex change has broken the program, it's as likely the problem is in the application than in the patch that was applied, and you should expect that the program is going to start breaking on distributions anyway since it is in upstream python (in fact I know for sure the version of python that comes with 16.04 has the fix in it, as I stumbled across this bug when I moved some code I'd developed on Ubuntu over to an instance based on a RHEL derivative and it broke)
