More specifically, there's this comment in zargs:

# Everything has to be in a subshell so that we don't "wait" for any
# unrelated jobs of the parent shell.

The "wait" is necessary to set the return status of zargs in (as
nearly as possible) the same way that xargs would do, so you can't run
current-shell actions with zargs.

What's the context of your question and your desired end result?
