As you may know: A) a target with no name defaults to the name of the dir it's in, and B)

path/to/dir

on the cmd line or in BUILD target

dependencies

is currently shorthand for

path/to/dir:dir

. These are legacies from v1. However in v2's file-centric world, we want

path/to/dir

on the cmd line to mean "all the files under `path/to/dir`" (this is what it means for pretty much every underlying tool). And, in that proposed future, we're pondering what

path/to/dir

should mean in BUILD target

dependencies

. Basically, we're wondering about how to get from here to there, and how much deprecation to do. This affects existing users, so we welcome your opinions: https://github.com/pantsbuild/pants/issues/12286
