When considering a stable OS, a year is not that long a time.

There was considerable discussion surrounding bumping the minimum 
versions for MySQL and PHP version requirements. The big concern was 
around which distributions and distribution versions it would obsolete. 
The choice in Qt version has the same issues. Did I miss the discussion?

For the user community, the difficulty in bumping the minimum required 
version of a package is more about how new the version is rather than 
how often it is bumped. If the version is too new, then it causes the 
problem that will be caused by using Qt 4.3 or 4.4: people will have to 
build custom Qt packages that are not part of their distributions.
