Comment 121 for bug 974480

mpt, that doesn't seem to me a reason why we can't have a drop down area for legacy apps. Yes their behaviour will be unpredictable for Ubuntu but it would still work for legacy apps.
I run a corporate repository for 6000 users and we are having to fix each unity version so our corporate apps work, or we have to move to RedHat. The corporate owners have no interest in fixing the apps for Ubuntu, and won't give out source code, so they won't be updated unless they move to a new library which does it for them (which is equally unlikely)
