how to create and share (non core) mockups!?

Hi,

recently the tablesorter pattern has been removed from the mockup 
repository. (see https://github.com/plone/mockup/pull/540)
One comment suggested it could live on as an addon.
That let me wonder, where do/should non core mockup patterns live?

If found
https://github.com/plone/mockup-extra
but it doesn't seem to be used anymore.

Or should I create my own repository based on 
https://github.com/collective/mockup-minimalpattern
and share it in https://github.com/collective?

The tutorial on
http://plone.github.io/mockup/dev/#learn 
tells you to create new patterns directly in the mockup environment.
But if the mockup repository is only meant for plone core patterns, that 
doesn't seem to be practical to me.
Wouldn't it be better if the tutorial were based on 
https://github.com/collective/mockup-minimalpattern ?

cheers
Dominik
