Because of compatibility with black this should be taken into account: https://black.readthedocs.io/en/stable/the_black_code_style/future_style.html#using-backslashes-for-with-statements

As of python 3.10 with statements can be parenthesized.

You are right.

Therefore the check should probably either run differently depending on the version of python that is targeted (pre vs. post 3.10) or have an option to allow backslashes in with statements.

On the other hand the special behavior is an edge case and becomes kind of obsolete in 2.5 years with 3.9 eol. So I can fully understand when the special behavior is not implemented. I do not know how much work that would be to implement. Unfortunately I currently have no time at hand to dig in to this.
