If we want it to be the default, it must be able to fallback on the current

Right. It seems like encoding=None is the right way to go there.
encoding='BOM' would probably only work if 'BOM' isn't an encoding but
a special tag, which is ugly.
I would rather see it as the default behavior for open without an
encoding specified.
I know Guido has expressed a preference against this so I won't continue
to flog it.
The current behavior however is that we have a 'guessing' algorithm
based on the platform default. Currently if you open a text file in read
mode that has a UTF-8 signature, but the platform default is something
other than UTF-8, then we open the file using what is likely to be the
incorrect encoding. Looking for the signature seems to be better
behaviour in that case.
All the best,
Michael
