Yes they want to build the graph of dependencies, which will be
potentially false, as I explained.

So you are fine with publishing "slightly incorrect" metadata at PyPI
? I am not.

The can have those data, by downloading the tarball of the project and
running the egg_info command. They will in this case have accurate
data in fact. So right now you don't deny them the data, it's one
command away from them.
I don't understand the rational behind providing flawed data at PyPI.
I am -1 on that.
