There are some unintentional consequences of convertingsqlite3.connect() to Argument Clinic in#40956.

1. Thedatabase argument always converted to bytes.
2. Keyword arguments are passed as positional arguments tofactory().
3. If an argument is not passed tosqlite3.connect(), its default value is passed tofactory().

It all works with the defaultfactory=Connection, butfactory can be an arbitrary callable, not completely compatible withConnection(). There may be a user code which uses a factory which only works with stringdatabase and does not support theuri argument. It worked fine in older versions when it is called with correct arguments, bet will become failing in 3.11.

This is a hypothetical scenario, but we should at least add a note about potential incompatibility. And I think that it is better to get rid ofPyUnicode_FSConverter here.
