These sound awesome! With the obvious note that the last_x values should
only be updated when rebuilding children is complete, so that if the build
is interrupted, they won't be forgotten to require rebuilding. (Or a more
fine-grained, per-children build state could also be stored.)
I personally don't care if the build breaks on an intentional 'touch -t',
I'd be happy to see either of these solutions!
Is there any realistic ETA on this feature?
Thanks a lot,
