Why is that? Nobody has to change anything.

Right. But those changes will no author of extension modules force to
change anything. The PyRun_ functions now expect const char*. Existing
code will pass char*. No problem, this is well-formed C. In addition,
people who want to pass const char* can now do so without using a cast,
which they previously couldn't. The only necessary subsequential change
is *inside* the PyRun_ functions, where the types of local variables had
to be changed, and the types of PyParse_ functions, etc.

Developers of the Python core have to keep this in mind when changing
the Python core. Nobody else has to change anything.
