This Is Why We Can't Have Nice Things

I do wonder if a GitHub hook could be used here. Peter's done some great 
things with them in terms of PR review, CLA checking and CI via our 
'vulcanbot' build system.

If PRs which contain stacks were monitored by vulcan, it might be able 
to pick up when they aren't going to merge due to binary reasons and 
provide a link to a page which shows the diff so at least the review 
process could start and provide feedback to the submitter. It would 
still be a chunk of work to integrate such things (as if the target 
stack had changed since the submitted stack was modified, you can't just 
copy the submitted one over the target one) but at the very least that 
would give a list of changes that need to be applied.
