and any particular reason that parallelism seem to be linked only to sorting? surely there are other kinds of processing that too can benefit from parallelism?
Historically, parallelism was used more for queries as well. However, new access methods introduced in 15.x were generally more efficient single-threaded than the older methods were using the parallel techniques, so for the moment at least they don't get much action.
They are used still used by dbcc checkstorage in partitcular.
