Great, if that's the reason then I'm happy and it sounds like there just
hasn't been enough demand for this or the resources to do the work
required for this, rather than a policy or technical reason.
The thing is I don't just want to backported version to be able to
co-exist next to the stable version.
What would be a win for me is if the stable version got the same
treatment as the backported version and didn't provide php5, but
php[stable-version] and got installed in paths/files called
Which in my opinion would make packaging and supporting the multiple
versions much easier.
At the moment we have what we need to support php5.6 on wheezy (we
deviated quite significantly from the php package structure this time
around so can't contribute it unfortunately), so we're happy.
I was really just asking to see if there is a way to make the process
easier for the next release upgrade.
If there is enough excitement and demand for this and if we can work
with you guys for guidance and to assist with the stable package
refactor, then we'd be quite happy to contribute to the maintenance of
the backported version.
