Maybe it is not a question of the maturity of the implementation but that of the person making presumptions of it.
I consider a fully pruned blockchain being equivalent to the UTXO. Block that hold no
more unspent transaction are reduced to a header. There is however no harm if more retained.

Which transactions are pruned can be rather custom e.g. even depending on
the wallet(s) of the node,
therefore I guess it is more handy to return some bitmap of pruned/full
blocks than ranges.
This isn't at all how pruning works in Bitcoin-QT (nor is it how I
expect pruning to work for any mature implementation). Pruning can
work happily on a whole block at a time basis regardless if all the
transactions in it are spent or not.
