WPS508 on negating chain comparison about wemake-python-styleguide

if a > 6 or a <= 4: :)

Yes, but that's not a chain condition, which is the whole point of this report.

Forbid not with compare expressions.

This is exactly what this rule does. Or am I missing something? :)

[Xoriun]

This rule forbids something like if not a < b since it can be rewritten as if a >= b. Here, the second version is clearly more readable which is (as I understand it) the reason for the rule - readability.
But for chain comparisons like if not a < b < c there is no way to rewrite it without not but still maintaining the chain comparison. Removing not leads to something like if a >=b or b >= c which (at least for me) is quite a lot less readable than what I had before. I would be fine with negated chain comparisons needing parentacise around them like if not (a < b < c).
