One of the maintainers of Extism here! Thank you for the kind words.

As you know, we're all about delivering value with the actual standards today. This means using truly portable, w3c Wasm core modules. Not some "maybe in the future" standard a la Components.

If you realistically want to use Wasm everywhere, in practically every language, Extism is the way to go and we're in it for the long haul.

For those who appreciate the WIT IDL being worked on (now for way too long), we support a far simpler, more familiar OpenAPI based version to eliminate the boilerplate of type conversion & serialization across the guest-host boundary, worth checking out: https://github.com/dylibso/xtp-bindgen
