I have succumbed to the temptation to implement various aspects of this. I have also tweaked existing implementations for my day job. I even had the assignment to pitch an implementation to a client. So I am sure that some would question my sanity NOW. TFA suggests that I might not have been sane to start with.
I admire any team-of-one that takes on this endeavor and publishes their work.
This article appears to be entirely about an implementation from scratch.
It makes very clear that it is not about forking Chromium.
But even Google was smart enough not to start from scratch.
So again, I don't know who the intended audience for this article is. It's advice on something no sane person or organization would ever do.
