Technically this is the additional syntax -- we always have "generator" syntax for non-file-based targets, like in 2.10+

python_requirements

will generate

3rdparty/python#Django

instead of

3rdparty/python:Django

. So we'll have 3 syntaxes: • normal one for explicit targets • file addresses • generated targets I still think it's useful to consolidate to just two syntaxes (https://github.com/pantsbuild/pants/issues/12917). But I wasn't persuasive enough and I see benefits to file addresses
