I also only use IE if I have a problem with my default browser (Firefox), and even then just to check whether the problem is with Firefox or the website I am having trouble with.
I have no problem ignoring ALL updates to IE11, and when I do have to use it, doing so in a sandbox.
My concern is that MicroShove has now crossed a very clear line, and will no doubt be using Windows security updates as trojan horses with increasingly vague mentions of "nonsecurity-related fixes" which will become "other critical issues." Because, after all, getting folks onto Windows 10 whether they want it or not is critical to MicroShove's plans.
It is starting to look like the day I will start using my Windows 7 computer offline only (and something Linux-based online) will come sooner than I thought. Oh well, it's been a decent run for a couple of decades (a few if you count DOS), but all things must pass...
