There have been a lot of changes & discussion about our modeling of targets, mostly thanks to the new feature of "target generation". https://github.com/pantsbuild/pants/issues/13160 summarizes where we're at, what remains, and what I would like to try to get into Pants 2.8

thanks: will look first thing tomorrow.

Great write up/summary. For me that have only followed the topic briefly this gives a valuable overview.

looks good, thanks. added a few comments, but that seems reasonable for 2.8
