Overview

Following conversations in#7997 and#9783 (comment): we'd previously added aparserOptions.jsDocParsingMode that API consumers can use to skip parsing JSDoc comments. JSDoc comment parsing can be quite expensive.

We'd previously been blocked from doing so because at least one popular ecosystem project,eslint-plugin-deprecation, uses them. Our initial version of adeprecation rule does too:#9783. So this issue is blocked until we create a suitable alternative, such as our own quick regexp parser.

See also#7906 for tracking running a performance comparison.
