Ok. This is news to me. Feel free to evaluate if you can build on top of the 
100 scopes project. AFAIK it's all GPLv3.

I agree that this would be desirable solution. But I think doing the "big 
thing" in this regard would for sure break all deadlines and time plans. 
Here's again the totally not matching time to marked requirements from KDE and 
Canonical which make things hard to even get started.

You have a point here... noted.

No. But the difference here is that those examples are quite stable or have a 
huge community by themselves while KF5 is still in early stages and before 
Blue Systems announcing its support for it, it was mostly 3 (or so) guys doing 
KF5 in their spare time. That does make a difference in terms of needed efforts 
to incorporate something.

There is... But exactly those are the ones that need to worry about deadlines 
and additional risks. So unless the developer says "Yes, I can do this" on its 
own, they won't force anyone to go through the additional efforts I mentioned

I don't know to be honest. Haven't done the homework to go through KF5 and 
check what it offers myself yet.

Exactly, we're ending up again at *additional* effort. Which is really 
something that does not go well with tight deadlines.

Fully agree.

That said. I try to make a good example by doing the Marble port for Ubuntu 
Touch in marble's git repo, by writing my phone apps in a way they can be used 
as a Plasmoid and a phone app and promoting this way of working on the ubuntu-
phone mailing list. Still, I can't force other people to do the same and I am 
not Canonical management. Also keep that in mind when reading my mails. It's 
my personal views on things trying to explain the situation as it currently 
is. I'd be happy to be proven wrong and see more of those good examples
