There is a compromise you have overlooked in your first contention. If you size the frame to accept a longer dropper at max depth you that will mean shorter riders wouldn't be able to lower their saddle enough, because the seat collar would be higher, assuming the shock position can't be lowered. Almost always there are compromises to be made.
Edited. The above is now what I meant. Edited.
