No it won't.  It's perfectly fine for code to assume the that a length
is a number, and people will continue to do so.

If somebody abuses __len for weird uses, it's their responsibility to
deal with the fallout, not the language's; they'll just have to make
sure their funny object doesn't get used in a context where it will be
assumed to be a table or whatever.

You're worrying too much.
