I guess we are talking different things here.
I have no problem with a Queue package paraemtrized by an Element type
(specified as private). Even novice Ada programmer must know how to
instantiate such packages if he uses Text_IO.
What I dodn't like is the need for several, possibly nested, instantiations
simply to get a simple queue or hash table.
