Subtle backward incompatibility in PEP 725?

I couldn’t find a specific topic about PEP 725 – Specifying external dependencies in pyproject.toml on DPO [1], but in reading it over recently, I wonder if there is a latent backward incompatibility.

This can probably be a standalone thread, but I’ll just point out: there is a link to the Discourse thread in the Discussions-To part of the PEP header.
