A toggle in chrome://flags to disable all omnibox suggestions (including history, bookmarks, search engine, etc.) and autocomplete

[amp123456789]

Hi,
It's a feature that exists in Vivaldi, Brave and Firefox in their settings. In those browsers you can turn off all these suggestions individually.
I'd really rather use Chromium or something close enough to Chromium like your Thorium browser (MV2 support is a major selling point), because these other browsers I mentioned have their own significant bugs that don't exist in Chromium.
However, the lack of the ability to turn off all suggestions and autocompletion/autofill in the omnibox / URL bar is a deal-breaker, I find all these omnibox suggestions very distracting. I personally don't want to see anything at all popping up or autocompleted when I'm typing up there. Being able to disable all these parts individually would be ideal (e.g. history, bookmarks, search engine suggestions, autocompletion) for others to be able to tinker with, but that's maybe too much work to implement, a single toggle to turn it all off would satisfy me.
I'm of course not the only one who wants this feature: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 and countless more.
I asked the Chromium team recently if they'd be willing to add it, they said they're not interested.
How about you, any chance of this?

I'd imagine the relevant files are:
https://chromium.googlesource.com/chromium/src/+/HEAD/chrome/common/chrome_features.cc
https://chromium.googlesource.com/chromium/src/+/HEAD/components/omnibox/browser/autocomplete_controller.cc
https://chromium.googlesource.com/chromium/src/+/HEAD/chrome/browser/about_flags.cc

Maybe something like the following for the above files, I don't know, just guessing:

BASE_FEATURE(kDisableOmniboxAutocomplete,
             "DisableOmniboxAutocomplete",
             base::FEATURE_DISABLED_BY_DEFAULT);

void AutocompleteController::Start(const AutocompleteInput& input) {
  if (base::FeatureList::IsEnabled(features::kDisableOmniboxAutocomplete)) {
    return;
  }
  /* ... */
}

{
    "disable-omnibox-autocomplete",
    "Disable Omnibox Autocomplete",
    "Disables all address bar autocomplete suggestions.",
    kOsDesktop,
    FEATURE_VALUE_TYPE(features::kDisableOmniboxAutocomplete)
},

I think omnibox suggestions and autocomplete are probably useful to most users, but adding an on/off switch for these features wouldn't be difficult, but this task has a lower priority.

Cheers, no rush at all, actually I found out 32-bit Firefox for Windows in the last few months seems pretty good and fits all my needs, it doesn't have memory leaks like 64-bit Firefox (e.g. GPU process is always around 500MB, previously it would always climb to 2GB, and the occasional rogue tabs exceeding 2GB will just crash, which is how I want it, instead of taking up all physical memory and turning the PC into a slideshow by swapping to storage virtual memory). However one day they may discontinue 32-bit Firefox and I'll be forced to find a Chromium-like browser.
