Support multiple separators looks easy, I don't expect any performance impact.
Like we already have it for strings: s.startswith(('\n', '\r'))
Regexps are more expensive thing, callbacks are kind of evil.

Andrew Svetlov added the comment:
For derivative Python implementation there is a standard strategy: they uses a
copy of CPython standard library.
Tthat's why any new module should have a pure Python implementation and that's
why https://www.python.org/dev/peps/pep-0399/ exists.

Yes.
For designing from scratch copy() is not necessary but if we have it for decade
