I think others would benefit of having an estimated time to build too, for example those that upgraded to High Sierra. I don't know if the buildbots are building the binaries in alphabetical or most downloaded order.

I don't know the stats, but ports could really use some diagnostics, like analyzing dependencies and telling beforehand of any outstanding tickets (broken ports or conflicts), not installed compilers that would need to be built from source — that kind of stuff.
