Comment 10 for bug 693303

In order to properly test a backport for PHP in Lucid, all of the reverse dependencies (install/run test http://paste.ubuntu.com/930490/) and build dependencies (build/install/run test http://paste.ubuntu.com/930491/) would need to be tested (which is over 100 last time I checked) and I haven't seen anyone willing to do that work yet. With the new PHP release process (https://wiki.php.net/rfc/releaseprocess), backports and SRUs become more of an option as they're less likely to introduce breakage, but the full testing would still be required at least for backports.
