Yeah... Krita's license is past praying for. We've had so many people who've worked on it, some of whom have gone and disappeared to find themselves in ashrams and kibbutzes. Krita's license is not going to change -- but nothing else links to Krita's libraries, so that should be fine.

That's probably not the first step. Though, in fact, it's one of the long-term plans: to make calligra into a platform and a set of applications.

I would like to see that.
