I think you are missing the point.  I'll try to rephrase it:

It is short-sighted to expect you can fully spec something as large as
workers.  This is a significant new concept, and we are only
scratching the surface.

So why back ourselves into a corner?  Let's be smart about the API
design, and allow for future flexibility.

I don't see any downsides to the approach outlined above.  If you have
something specific in mind, please let us know.
