The POSIX requirement only applies to portable uses of the builtin - ie.
those that are prescribed by POSIX. Since POSIX does not require \e,
dash is not failing compliance, even if it differs from extensions
provided by corresponding executables. I do not think dash needs to
bloat for \e unless POSIX standardizes it first.
