> I don't have data but I would guess that making common options larger and/or putting them on the home tab makes them more discoverable.

At the expense of non common options, which become undiscoverable.

When I open a software for the first time I'll often scan all the menus once, to get an idea of supported features and their categorization. I'll randomly rescan the menu from time to time when I feel like learning something new/want to further my expertise.

That's an interesting approach but it seems invalid for Office. The have thousands (!) of features. Going through the old menus wasn't much help. More than that, they're actually exposing more functionality through the Ribbon. For the truly hidden commands, they have the Options menu, under the Office icon.
