Why isn't indexing_slicing a restriction ?

[gnzlbg]

It enforces a coding style that does not make sense for every crate, and it should IMO be opt-in, even with -D clippy-pedantic.

To me this lint is similar to integer_arithmetic. Both of these lints suggest that you forgo basic features of the language (i.e. indexing and arithmetic operators) in the name of safety. integer_arithmetic is in restriction.

[gnzlbg]

The same applies to shadowing, for example.

This lint got moved to pedantic not long ago. Relevant issue: #2536, PR: #2790. I don't really have an opinion about restriction vs pedantic for this lint.

That seems like that was to be in accordance with the issue, but this definitely looks like a restriction lint and is under restriction in the clippy rfc. I'm in favor of switching back

@oli-obk thoughts?

Yea... I guess I was confused. Restriction makes more sense
