One thing that would probably help would be to fix reifySingleData to return Some of the Data when that Data is not a view, namely tweak this line:

chisel/core/src/main/scala/chisel3/experimental/dataview/package.scala

Line 268 in 2f9faa2

case Some(_) => None

That should become case Some(_) => Some(data)

But we really ought to add an alternative to reifySingleData to return Either[Seq[Data], Data], where Right[Data] means it's a single Data and Left[Seq[Data]] means it's more than 1 Data, and that Seq is the Data it reifies to. Would be super helpful for error messages and things like .toString.

i guess i'd rather get this actually working for one of the aggregate cases before worrying about which reify to use... i am bashing my head against why FlatIO does not work for probes
