"unknown/undefined" semantic token type

[benblo]

It would be great if any token that is not recognized would be tagged with an "unknown" type, so we can configure coloring rules for them.
For example:

class Test:
	def __init__(self):
		self.my_attribute = 0

test = Test()
test.my_attribute
test.doesnt_exist

print(doesnt_exist)

Here , using the scopes inspector, my_attribute is identified with the semantic token type "property".
But, doesnt_exist has no semantic information at all:

By default, my_attribute appears blue, while doesnt_exist exist appears white, but if I wanted to highlight it in red or grey or something, what semantic rule am I supposed to modify?
It feels like this goes under an "anything" umbrella; I would rather have a "known to be unknown" type.

Similarly, unknown globals are identified by the analyzer with a yellow squiggle, but they also don't have any semantic information:

I would like to be able to change their coloring, eg if analysis is suppressed somehow (for example with "reportUndefinedVariable": "none").
