I agree.

The machinery exists, but we'd still need to decide which variables
should be "injected".  Once we make that decision, do we really need
all the heavy lifting that Async lets us use?  Because adding --eval
to the command line for each variable is not really rocket science, is
it?

Bottom line: I don't think we need to wait for Async being in core to
solve this issue in a very satisfactory manner.
