Noted :)

Relicensing is a possibility, and one that happens a fair bit in git.kde.org 
to allow for code sharing (GPL -> LGPL being the common change)

Yes; it is a balance between being hospitable to individual creators and 
maintaining a healthy community. We’re probably in fierce agreement on that 
point :)

If we were to make a policy change, we could outline the challenges of GPLv3 
code in a largely-GPLv2-world in the policy page while still allowing creators 
to individually opt for it.

This is not limited to GPLv3, of course, but also GPL->LGPL (for instance). 
This is one of the reasons KDE e.V. introduced the FLA agreement, so that if 
people do go away we can continue to manage the licensing of the code within 
the boundaries set out (must be Free software, stick to the licenses in our 
policies, etc.) I hope that a large % of KDE community members have signed it 
by now as it resolves this exact issue.

We already have this issue today. As I noted in a previous email just a couple 
days ago I received an email requesting that I approve a relicense of come 
code I wrote from GPL to LGPL as it was moving from an application (that was 
GPL) to a library (which obviously needs to be LGPL). Relicensing applications 
as they grow and differentiate is part of what happens. There are also 
libraries that are GPL in git.kde.org, btw, they just don’t make it into the 
base KDE libraries due to our (imho sensible) policies in that area.

Ok, understood.

I honestly don’t see the base value that is changed here: it’s Free software, 
etc. It would be a change in application licensing policy.

+1

Yes, the Linux kernel runs full-on into the patent and tivoization issues 
which make GPLv3 undesirable for them.
