I think it's fine to drop support for the original PCRE.  All supported
versions of CentOS, Debian, Ubuntu, FreeBSD, and NetBSD have PCRE2 by
now, and I'm quite fine with giving folks using systems without security
updates a bit of a wake-up call.  I have no reason to believe that any
other major operating system won't have version 2, either.

So, essentially, I think this is a good idea.
