just to be clear @JonathanBrouwer, is the behavior right now exactly the same as before with regards to errors and which attribute applies in case of duplicates or not?

@jdonszelmann
The behaviour regarding errors and duplicates is exactly the same when multiple identical attributes are specified. This provides a warning "unused attribute" without stating it will be removed.

When multiple different attributes are applied the behaviour has changed. This is fine because [used(arg)] with an argument is unstable.

What has changed:

#[used]
#[used(linker)]

Before: Error, "compiler and linker can't be used together". This is a wrong error since #[used] should be equivalent to #[used(linker)]
After: Changed: now a warning, unused attribute

#[used]
#[used(compiler)]

Before: No error, ratcheting behaviour so "linker " is used
After: unchanged

#[used(linker)]
#[used(compiler)]

Before: Error
After: Changed: Now also does ratcheting to linker.
