+Poetry_ has said they would **not** support the PEP as-is because
+`"Poetry supports sdists files, directory and VCS dependencies which are not supported" <https://github.com/python-poetry/poetry/issues/4710#issuecomment-973946104>`__.
+Recording requirements at the file level, which is on purpose to

+`"is contradictory to the design of Poetry" <https://github.com/python-poetry/poetry/issues/4710#issuecomment-973946104>`__.
+This also excludes export support to a this PEP's lock file from
+Poetry as
+`"Poetry exports the information present in the poetry.lock file into another format" <https://github.com/python-poetry/poetry/issues/4710#issuecomment-974551351>`__
+and sdists and source trees are included in `poetry.lock` files, thus
+it is not a clean translation from Poetry's lock file to this PEP's
+lock file format.
