Typically if you’re creating a composite type, you’re planning to store
data in that type, so you’re probably not going to just drop it without
an appropriate migration strategy around it, which would (hopefully)
prevent the above case from happening.

I wouldn’t let this block the release, so +1 for removing from open
items.
