Bug#1000082: glib2.0: depends on obsolete pcre3 library

[Andreas Henriksson]

Hello,

My 2c is that what will likely happen is that glib upstream declares
GRegex deprecated (since porting it to pcre2 will also be an ABI break
AIUI). The soname will stay the same and downstreams will have to decide
if they offer the GRegex symbols or not (or possibly runtime linking of
pcre3 if it's available).

I think the likely way to get rid of glib dep on pcre3 is to start with
a MBF against all GRegex consumers and ask them to move to pcre(2).

(Once we no longer have any in-archive users of GRegex I bet some people
will want to argue the case for keeping it because of out-of-archive
software might still use it.)

Someone will need to offer to do the MBF which likely also comes with
taking on the work to write some kind of porting guide.

Regards,
Andreas Henriksson
