Review comment:
If something isRequired, doesn't that mean it could still be potentially
trailing if eveything after that is optional? So the algorithm should always
just be something like:
1) find that last required element
2) this element is potentially trailing if it is that last required element
or appears after it.
Also, this doesn't take into account this like if the
nearestEnclosingSequence is ordered or or unordered. This also feels very
similar to couldBeLastElementInModelGroup. Are there subtle differences between
what those are asking about?
