Then perhaps we're not at odds because full JS-disable support is often unreasonable. My gripe was that many of my own experiences using uMatrix with scripts disabled by default ('cause you never know what sort of modals and pop-ups and other junk random pages send you) and not getting even the slightest feedback on what went wrong. I'm aware that this is a minority setup, but throw a user a bone. I've been banned from signups because I failed a third-party CAPTCHA I never saw. I enable JS manually on almost every site once I get an error and it's vaguely trustworthy.
