Thanks for the explanation Steve.
We talked with some SEO expert about this argument and we was told that having URLs such as yours with language tag:
mysite.com/en-us/producta
mysite.com/en-in/producta
mysite.com/es-us/producta

is not useful having also the hreflang map. It's only useful for cases where the urls are duplicated, i mean same urls but different languages in the page contents. Your urls are not duplicated.
However if you have consistent arguments and hints about the utility of this map, please post in the wishlist and we will evaluate again this development.

Thanks a lot,
John
