Hahaha, yeah, and of course you'll get everything you want with all that politeness.

There are no additional mouse clicks, a menu bar would require 1 click to open the menu prior to access to any item anyway.
There is only 1 additional hover at most and that's only for the obscure more tools menu whose only option you'd touch more than once in your lifetime is "Clear private data" that can be also accessed via Ctrl+Shift+Del.
