For replacing:
- glibc is smaller
- glibc might be faster (but I have not benchmarked. And anyway, if
  speed matters, we should optimize regexes away completely. Like in
  CapabilityImpl::parse [*])

Against replacing:
- it is not a regression compared to 10.1 or 10.2
- using a different regex engine might cause bugs because of
  slightly different regex dialects.

My conclusion is not to change it for 10.3
