Suggestion: warn on using EqualExportedValues for proto messages #282
Description
This might not be suitable for everyone, but the ability to turn on this functionality would be nice:
Currently, assert.EqualExportedValues is often used to compare proto messages for equality. With the new Opaque API of proto, all fields will be unexported, so this assertion will assert nothing.
The problem is that people might migrate from the open to the opaque API without noticing that they still have these assertions in their tests. So having testifylint warn you about it is a useful feature in my opinion.
