media library grid bulk actions

Are there plans to allow developers to extend the bulk actions drop-down on the grid view?

I noticed on https://core.trac.wordpress.org/ticket/28842 that the Bulk Delete was only recently moved back into a drop-down, so I understand that things are still fluctuating a bit.

However, if it isn’t intended to let folks extend it, and Delete Permanently is the only option, I wonder if this comment begins to make more sense: http://make.wordpress.org/ui/2014/07/22/media-grid-user-testing-round-1/#comment-24457
That would make 2 clicks instead of 4, and you’re still asking the user for confirmation before they blow up anything.

At any rate, I’ve managed to add my own ‘Bulk Optimize’ action via javascript, replicating the method I borrowed from viper007bond’s regenerate thumbnails plugin. Unfortunately, it actually attempts to delete the images, because the drop-down on the grid mode is js-based, instead of submitting via POST like the old one. I barely know enough js to be dangerous, so any guidance here would be appreciated.
