Are you sure you "failed"? Maybe there was good enough compatibility and that wasn't the problem?

The problem sounds like a business 1 where you're after more users and you deem this "magic compatibility" is fixing it. Well maybe that's not it.

A lot of people tried Deno and even tried to build libraries for it back some years ago. What you "failed" at is building the traction, ecosystem and community support.

Compatibility doesn't buy you moat. Deno specific ecosystem, libraries and services etc do.
