I don't think it should require pip, and after installing python3-pip here and re-running /usr/bin/pyproject-build I noticed that it (obviously) invokes pip and downloads several things, which IMO is a no-no. The reason I packaged python3-build is because check-manifest started depending on it. I'm thinking about removing the /usr/bin/pyproject-build program and just shipping the library. Do you think it could work? (Sorry, I'm not a PEP-517 expert).
