Opposite of increment-decrement (for non-loop-counter usage)

[scop]

Is your feature request related to a problem? Please describe.

The increment-decrement rule is quite opinionated, as many rules are. However, its suggestion is problematic in the sense that e.g.

• it's not that common of a practice in my experience to use ++/-- in contexts other than loop counters in Go code, e.g. stdlib
• many programming languages don't even have those operators (for example Python, Rust, Swift, Zig)

Describe the solution you'd like

increment-decrement can be disabled like all others, no problem with that, and that does not require a solution.

But for the above reasons, a rule that would do the opposite of increment-decrement for anything but loop counters would be nice to have.

Describe alternatives you've considered

Just disabling increment-decrement, but that won't help with adoption of the += 1 style.

Additional context

N/A.
