I don't see why it is a "lot" harder. It might take 5 lines of code
rather than jumping straight into the ROM, but it doesn't seem like huge

It gets excluded as part of a broader test which also prevents any
table, but specifically the LDT, from referring to an LDT (on the
grounds that its hard to reason about, and may be undefined).
