in the documentation of the distutils module, there is a cyclic references, just remove them because I think it's useless.

This is a common pattern in our documentation.  It is done because ":mod:`xxx`" means that xxx should be formatted as a module name, rather than anything else.  While it is true that the formatting for most such references is currently the same, it could be different in principle, and is for a few.  It is in some ways unfortunate that it also always results in a link, so you will indeed find a number of places where the prefix is omitted, mostly commonly when the same entity is referenced several times in the same paragraph.

So, it is not completely clear cut, but I would recommend rejecting this and leaving the docs as is.

ok, it's fine for me, I close this issue
