Curious About Lack of Developer Licenses or Multi-Paks

I would imagine this has been discussed at length somewhere, but several search attempts here didn’t turn up anything. I am just curious why Envato has never created Developer Licenses or Multi-Pak Licenses. It seems that these would be even more popular than the ‘Extended’ licenses which are for use in another product.

I am hoping someone can fill me in or point me to a discussion elsewhere.

Yes +1000 for the multiple domains license pack idea.
