I'm pretty sure what needs to happen here is to have exactly one package
providing phpapi-20121212.

You are quite right. I have prepared an php5 upload where only php5-common package provide phpapi-20121212 and the Provides: part have been dropped from various SAPIs.

This will of course break all packages depending only on php5-<module> without declaring dependency on php5 (or specific php5 SAPI). After cleaning the list (grep-dctrl generated) by removing php libraries and various optional modules, where the php5 dependency is provided by main package (like fusionforge, mediawiki, nordugrid, horde), I have been left with this list:

> Package: bandwidthd-pgsql

> Depends: dbconfig-common, php5-gd, postgresql-client, ucf, debconf (>= 0.5) | debconf-2.0, libc6 (>= 2.14), libgd3 (>= 2.1.0~alpha~), libpcap0.8 (>= 0.9.8), libpng12-0 (>= 1.2.13-4), libpq5

> Package: davical

> Depends: debconf (>= 1.0.32), php5-pgsql, postgresql-client (>= 8.1), libawl-php (>= 0.53-1~), libawl-php (<< 0.54), libdbd-pg-perl, libyaml-perl

On the other hand it will fix all packages declaring "Depends: php5-<module>, php5" since the php5 SAPI dependency will be correctly resolved by dependency order in php5.

We might be able to do the same for wheezy if we can push the fix for bandwidth-pgsql and davical to wheezy in the same run. That's probably up to release team to say if they would ack such action.
