This rule is causing confusion and I don't think it's very helpful. Can it be disabled by default?
Short names are not inherently bad, particularly in short blocks.
The main point against single-character names is that variable names should ideally be descriptive. This is more relevant when used in bigger scopes. But that's a bit mute when declaration and single use are just a couple of characters apart. Then it can be more like a unique identifier without much embedded contextual information.

Disabling it by default is a viable option, let's do that.
