The problem is that you don't know *when* you'll need to distinguish
Situations where things are not obviously incorrect, but only subtly
incorrect, are a common source of practical problems. Choosing the
full set of Unicode identifier characters as the identifier character
set for everyone puts nearly all Python users in that situation.
That's what the issue is here: defining correct practice to be
something sufficiently difficult that almost everyone's regular
practices are subtly wrong in ways they don't fully understand.
That's a recipe for bugs, vulnerabilities, confusion, etc.
The loadable table that you proposed, and Jim proposed, really sounds
like the best way to go here. Those that are ready and able to handle
the added complexity can voluntarily adopt it, and those who don't (or
don't even know about it) won't have to deal with it.
