As a user of Ubuntu, I would certainly prefer if the faster
implementation was used (which is Boost.Regex).

That said, I think it's not so much a choice of Ubuntu (or Debian)
package maintainers but rather that of the upstream projects.

Somewhat on that note, just recently I (among other users) reported a
KDE performance bug[1] which appeared in the latest Kubuntu and turned
out to be caused by std::regex. The currently proposed solution is to
replace it with a manual parser.
