>This is why gatekeeping is important and shouldn't be labeled as toxic.

I do not for the life of me understand your point. Gatekeeping, as its most commonly used, means controlling access to something (be it a resource, information etc) to deliberately and negatively affect others that are not part of a "blessed" group. Its not objective, and certainly is not a practice reliant on merit. Its an artificial constraint applied selectively at the whim of the gatekeeper(s).

>There's been a shift where everyone wants to welcome everyone, but the problem is it erodes your company culture and lowers the average quality.

The first assertion and the second one are not related. Being welcoming to everyone is not the same thing as holding people to different standards. Company culture sets company inertia and how employees are incentivized to behave and what they care about. You can have the most brilliant engineers in the world, like Google most certainly does have its fair share, and as we have seen, with the wrong incentives it doesn't matter. Look at Google's chat offerings, the Google Graveyard, many of their policies becoming hostile to users as time goes on etc.

Yet you can have a company with what you may deem "average quality" but exceeds in its business goals because its oriented its culture to do so. I don't think Mailchimp was ever lauded for its engineering talent like Google has been, for example, but they dominated their marketplace and built a really successful company culture, at least before the Intuit acquisition.
