I have to wonder if the variant is worth it. There is not going to be any
space savings, and in typical use, there isn't going to be much increase in
safety, either. So I'd probably give up on the variant in this case, because
I'd rather keep the aggregates (they are big help when a component needs to
be added). But only you can weight that trade-off, because the relative
value of the two options is something that depends on the components and the
intended uses. (If the "empty" variant wasn't going to be empty in future
version, for instance, the variant would make more sense.)
