I agree that that should be the case, but unfortunately people keep seeing UK-specific tagging guidelines and thinking they can wantonly apply them elsewhere in a completely different context where different distinctions are needed, just because all the tags are supposed to sound like British English. That’s how both zebra and uncontrolled came to have different meanings globally than in the UK. It didn’t help that the table was located on a global page, so I spun it out to avoid confusion.
Out of curiosity, are the crossing:markings=yes occurrences making it more difficult for you to query for underdetailed crossings? Just trying to understand the practical implications so we can potentially come up with a mitigation strategy.
