There is Bartender (http://www.macbartender.com/), which lets you shove all your non-critical menu bar items into a second menu bar like thing that you can hide away. So, while I have 18?? some odd status item apps running right now, by default I only really see the 6 or 7 most critical ones.
Bartender doesn't work with all status menu items, notably Chrome's notification status menu (maybe it's changed in the month or so since I last checked)... but Bartender "solves" the "GTFO out of menu bar" problem.
