Shouldn't we compare calendar here like for PlainDate#equals ?

On the one hand yes, on the other hand having different calendar values is currently not implemented...

PlainYearMonth doesn't have a calendar field yet, because as Philip mentioned, different calendars aren't implemented yet.

Yes, I know that different calendar is not implemented. However, I thought that if it would be needed in the future, it might as well be implemented in this PR for consistency with PlainDate#equals.

But I think this is a minor issue and will eventually be implemented and tested, so it is acceptable for me
