Comment 61 for bug 1779890

I can see why you do the purge forgetting the old state to enable them as if they were freshly installed.
I'm not sure how SRUable that will be afterwards as it is affecting behavior if someone has set something else than the default. But for now, going forward to mantic I agree that it will help to get an upgrading system out of the old wrong dependencies.

Given that this isn't meant to be enabled automatically (thanks for the explanation in the last patch) that should be ok'ish.

You do this change even to people which installed 3.4.3-1ubuntu2 as the first (which was correct). But I think adding more code to detect that rare case won't help many real cases.

Since this is juts for mantic for now, that is fine.
But double think about it on SRU time.
