As it stands I often don’t use dynamic arrays (and now ansistring) because of growing limitations, which is a shame really.
No. That would mean an additional entry in the metadata of strings and 
arrays and those are already big enough in my opinion compared to the 
data they're handling.
If one needs capacity based handling for these types then one should use 
helper types.
