Its not a huge a file-format change, just an additional string it will
recognise in the flags section. It shouldn't cause any harm if you have
an unrecognised flag (aside some warnings), therefore does not make the
file incompatible with older versions of PCB.

Always seems to be the way when you "fix" something.

Oh, we _can_ break them... ;)
The question is really just when we should, and what the balance of
pain / benefit looks like.
The developers are not operating under the rule that we will never
change behaviours, to do that would mean serious stagnation and possibly
eventual death of the project.
What we critically don't want to break, is existing _designs_, and of
course.. we can be sympathetic to views about behavioural changes.

The idea is that it is an improvement over both old and current
behaviours ;)
I pulled an old demo board, removed a couple of bits of power plane, and
was immediately able to see just how isolated and fragmented bits of the
ground system had become.
