Just to clarify the current policy is:
 - frameworks release 5.XX
 - plasma beta
 - frameworks release 5.XX+1
 - plasma final

Where 5.XX is the required version for Plasma. We set it as a dep,
just after it gets released.
We've had issues in the past, especially before frameworks had that
2nd Saturday of the month policy, but I don't think the current rules
have a problem if followed.

Within the context of this thread, we're dealing with issues that came
up breaking at 5.XX+1, so after the freeze. Not technically new API,
but behavioural changes.
