I've been a UK resident for over 70 years, have two degrees from a very well known university, and find both zeros and zeroes quite acceptable as the plural form. So our perceptions are different. Do we toss a coin, or see who can shout the louder? ... Dictionaries are less open to subjective bias than individuals because of the averaging effect of carefully controlled large surveys (and acceptability is usage driven). It's good to realise that personal preferences may not be the best basis for judging correctness.

If you want it to automatically check/fix lint errors like this, I would recommend setting up https://github.com/gabyx/githooks in your dev environment. We have a pre-commit hook that automatically runs rubocop for any changed files whenever you try to do a commit. I find it helpful anyway. (Nick prefers a VS Code extension that actually runs it every time he saves a file, which is oftener than I prefer but works for him.)

Other languages, German for example, are notorious for very long compunds like this and this, that are made up and written as one word directly. Perhaps the way your native language deals with compounds explains your (or other authors') personal preference and sense of "right"?
