New poetry version with many complicated changes but some simple things still missing

[ghpqans]

I'd wish the next version of poetry would merely focus on adding some simple things with high usage potential instead of adding many complex things for a little bit more usability.

E.g.

1. Version/Projectname placeholders in the pyproject. This point is, that the current behaviour enforces me to make use of a toml parser to output a simple present line like "Hello, this is tool X, version Y.Z". Therefore it would be better if there were an option to define the version/projectname within the sourcecode as a single source of truth and only reference it in the pyproject.

2. Option to specify path to alternate pyproject, e.g. one per subfolder or one per build target. This would enable building different something out of the same source tree without much hazzle.

Hatch is able to do that but has other disadvantages compared to poetry.
I think, when poetry would support this, it would convince many people using poetry instead of hatch.
