To be clear, this is what we're discussing:
> You may be gaining access to hidden gems, but you're definitely turning away proven and experienced developers from even entering your hiring funnel.
You're describing hidden gems.
My point was that for someone who is internet famous, more people will be willing to jump through hiring hoops, whatever they may be, just as they are for FAANG, but that doesn't work for most hiring companies, because most companies are small and you've also never heard of them.
Also, no amount of "works for me" argues against your process turning qualified people away unless you have some out of band way of knowing that that isn't happening.
