It is pushed now.

And the decision has been 'no'. There are two primary reasons:

GNU Parallel has done this since before it was GNU software. Changing
the default behaviour need extremely good arguments. In the history of
GNU Parallel a change of the behaviour has happened twice (namely -j9
=> -j100% and the behaviour of having multiple input sources
--xapply).

The author of GNU Parallel uses it for traceroute to multiple sites:

  parallel traceroute ::: pi.dk freenetproject.org

and here it is important that a complete job stays together.
