Comment (by kencu):

 having legacysupport be able to target systems older than the one it is
 building on would be desirable.

 but in practice there are lots of conflicts and questions that crop up,
 and we have not worked these through yet to a solution.

 I guess we could start by making a list of what the issues are that need
 reviwing…
