It's easy to make the mistake of adding omitempty struct tags like this (example from https://github.com/golang/oauth2/blob/master/token.go#L50C2-L50C44.):

Expiry time.Time `json:"expiry,omitempty"`

Currently, this does nothing. With encoding/json/v2 it might become omitzero.

I suggest to add a vet check flagging omitempty as error when added on time.Time non-basic types according to encoding/json's isEmptyValue (https://github.com/golang/go/pull/63533/files#diff-01d931f6d3bbaef911876952770a164229fe8d659b9007f4be9fc1ea12d20abeR306).
