List of the Linux distributions most interesting for us can be 
found here:


It looks like most have PCRE2 now.  Though obviously enough, there 
are at least some where there are no PCRE2, including Ubuntu 14.04 
which is expected to be supported till April 2019, Debian 8, which 
is to be supported till 2020, and CentOS 6, which is to be 
supported till 2020 as well.

So this is going to be the first real reason to actually support 
PCRE2.  Patches are welcome.

Well, this depends on your point of view.  If a project which 
actually developed the library fails to introduce support to the 
new version of the library - for an external observer this 
suggests that there is something wrong with the new version.
