we definitely don't want any IE support by default?
don't all of our apps set custom browser lists anyway?

Apps usually (should) set a default via a browserslist config file, yeah. I think that generally all of our libraries should default to a target that balances minimal compiled output and browser support. Including IE, though makes most of bugfixes useless since there is very little that can be fixed without down-leveling.
I think my position here is that libraries should not exclude ie11 support, e.g. should allow further compiling and polyfilling in the app, like we do for the browser support pages. I don't think a default set of browsers that includes ie11 here tho makes that more likely tho. Overall, new syntax can generally be polyfilled/down-leveled, the real issues are usually around subtle CSS differences or engine quirks, things that you don't uncover unless you are actually testing in IE
