What if someone would create a pull request to implement unlock origin natively inside chromium, instead of an extension. If such a PR met all technical criteria, would Chromium project accept it?
On the other hand Chromium is relatively simple to adapt with many real world examples to learn from.
(Personally I think they should stick with EdgeHtml but it seems that ship has sailed).
However, this does provide an opening for MS edge, if MS forks Chromium for Edge and excludes user hostile “features” such as this.
There is a quite a bit of adware which uses unsigned Chromium to push their wares.
That is the malware installs a modified Chromium with all the "extras".
So anecdotally, when I see Chromium on a users computer I assume the worst (that I have a cleanup task ahead).
On the flip side Chrome's profiles are nice and I wish macOS supported more of it.
