"Missing tag" validator doesn't take into account "disused" prefix

[GuardedBear]

When validating data, warnings are raised if there's a missing tag (e.g. "sport without physical feature"), however this doesn't take into account the "disused:" prefix.

For example, a sports pitch tagged:

disused:leisure=pitch
sport=tennis

is flagged with this warning. But I don't think adding disused:sport=tennis is the answer.

So I believe this validation should take into account features with a "disused:" prefix, and ignore them.

But I don't think adding disused:sport=tennis is the answer.

Actually I would think exactly that is the right way to go.

Hmm, I thought you just prefixed the main tag with 'disused' and left the rest as-is... But now that I read ​https://wiki.openstreetmap.org/wiki/Key:disused:* properly I can see that adding 'disused' to the 'sport' tag as well does make sense.
