~40% of my immediate fediverse circle doesn't know what an origin trial is. Probably fair to assume that at least 50% to 75% of web devs don't either.
Origin trials are a mechanism by which certain browsers let you use early experimental APIs in production, on your site, for some time.
This allows you to test the API early, as if it was already enabled.
And it helps us get feedback and make the API better for everyone.
