I think if we are going to deprecate type comments we will absolutely need to provide a switch to let folks silence this message. Based on the primer output, it seems (expectedly) that the usage of type comments are pervasive in some code bases. These code bases should be allowed to ignore this deprecation for now. I also think if we are going to deprecate type comments loudly we should link from the deprecation message to a page in the documentation about how to migrate a codebase using type comments to annotations automatically (or at least, mostly automatically). This page should mention things like the libcst codemod https://libcst.readthedocs.io/en/latest/codemods.html#libcst.codemod.visitors.ApplyTypeAnnotationsVisitor
