Well, in my understanding "ideal" unlike "exact" is just a suggestion and shouldn't by itself raise any errors if browser cannot satisfy a request. So it shouldn't make any difference for devices with less than two cameras where at least one camera has been marked as "front". I also suspect that in most cases only internal cameras will have this user-placement mark if OS even support that distinction at all. We can guard it by mediaDevices.getSupportedConstraints() but browser which doesn't support such constraint should just ignore it without raising any errors according to standard.
