No longer necessary to "include image descriptions on the page"?

When the Image Description Tool was first introduced, there was an issue that prevented ePUB readers from finding and playing recorded audio image descriptions. So you all added a check box to add the descriptions to the page:
I think that that limitation has been eliminated. ereaders now do find and play image descriptions that are not on the page. This may be a candidate for a feature that can safely be removed.
