I mean, you could just stop using Chrome if this happened, if you haven’t already. All the other popular browsers would be unaffected, and I’m sure projects like ungoogled-chromium would patch a change like that out.
Also all the other popular Browsers are either based on Chromium or based on Gecko, an engine that has no developers anymore since last year.
When I wrote about sustainability, that's exactly what I was talking about.
There are still more than a hundred developers working on Gecko.
Because I think there's a difference in assumption vs reality here. External contributors work in their free time and are, as I'm trying to point out in my other comment, unsustainable as a work model [1] [2]

The Gecko is drowning.
