Asking to tag segregated=no on highway=footway bicycle=yes is pointless

[mkoniecz]

What steps will reproduce the problem?

1. Create way with highway=footway bicycle=yes
2. Run validator

What is the expected result?

Nothing, as in this case segregated=no is obvious (and that is why for example StreetComplete is not asking people to tag segregated)

After all, if bicycles would have its own designated space, then it would be bicycle=designated, right?

What happens instead?

JOSM spams "missing tag - Combined foot- and cycleway without segregated. (18)"
