I can't get excited about it, and I definitely do not like your
suggestion of embedding particular assumptions about the lookup keys
into the API. What you've got here is a worse error message and a
recipe for proliferation of ad-hoc wrappers around SearchSysCache,
in return for saving a couple of lines per call site.
If we could just move the error into SearchSysCache it might be worth
doing, but I think there are callers that need the flexibility to not
fail.
