In this year, Qt3 has got a few QA uploads with the most relevant change being support to multiarch. And, more importantly, nobody seemed to care enough to step into maintaining it.
In the last days, I have taken a look into how much needed to be done to
remove Qt3 and there were slightly more than 50 packages depending
directly or indirectly from Qt3. A removal from Wheezy seemed doable
given that removing packages is never a problem during the Debian freeze
All the packages affected have a bug opened since more than one year and half ago and I have pinged all the bugs with some maintainers responding quick (thanks!). I also filed some removals for packages that were clearly unmaintained and didn't seem worth keeping, with ftp-masters responding quick too (Thanks!). And finally, a couple of QA upload for orphaned software that were still useful without Qt3.
There is a wiki page tracking the status of the removal if you are
If in the future, you are reading this and you need Qt3 in Wheezy, you can fetch it from Debian snapshots.
