There is also a lot to be said for going with what is known to be stable for an 
LTS release. While hopefully 5.4 will be perfect first time, any problems can't 
easily be corrected on a locked down distribution. 5.3 is now 'stable' .. sort 
of ... all of the changes are well documented and projects using PHP have had a 
good chance to incorporate the PHP5.3 differences. Those projects would not have 
time to update to 5.4 before Ubuntu had frozen those inclusions.

While 5.2 is no longer supported, it is still being used on frozen distributions 
simply because the projects it is supporting have not upgraded to 5.3. The 
various little incompatibilities that have occurred in the 5.3 versions - such 
as is_a - are the sort of thing that an LTS freeze aims to avoid ;)
