Has anyone considered extending dash?

If dash implements the Single Unix Spec, then it does not HAVE to do more to meet that formal spec.
But some of the "bashisms" are convenient, would add little to the size of dash, and would make it FAR easier to use dash as an alternative.
Is anyone looking into what bashisms are "most popular" yet small, and perhaps should be implemented in dash as well?
And, if they should, perhaps modifying the Single Unix Spec so that it includes those, too?
I don't think that dash should add everything that bash already does; we already have bash.
But it might be easier to use dash as /bin/sh if dash added a few of bash's conveniences.
