I'm sure it can.  But it shouldn't have been imported, because it
isn't a real world feature.

Not sure what you mean.  Why can't you just use the way id, and keep
the way id <-> TLID table offline?  (Yes, the mapping will get messed
up as people split and delete and recreate ways, but that's what's
happening with the TLIDs anyway.)
