Check closer. The TTx registers always exist. They have a different name on the ECs, though the register mapping is exactly identical (obviously).

No version of the 68030.library or 68020 was ever a no-op, excuse me.

It goes beyond that. Various graphic cards are affected as well. Look into the CVision3D manual, for example. It requests users to run "Enforcer" (back then) to have an operational card on the 68030.
