Align View to ACS - not available in ribbon/search field?

It seems Align View to ACS, as we have in the View Orientation toolbox, isn't available in the ribbon?

Also, a search in the search box in the top right corner doesn't seem to show it, as if it doesn't exist anymore.

I noticed this with a few other tool buttons too. I think (especially when they're not available in the ribbon) they should at least show in the search results?
