We currently give a special meaning to [NotNull] and [MaybeNull] on input parameters (see LDM notes), but we don't for their conditional counterparts.
We should consider doing that too, assuming that we can come up with a compelling example.

Note: if we do this, we should consider enforcement within method bodies and also in OHI.

Tagging @RikkiGibson who raised the question in #41336
