The problem is that the official superserver API is proprietary and unpublished - Dmitry reverse-engineered it which is not advisable for production use (and I doubt if it get's InterSystems' blessing): that's why Chris didn't take that approach and built his own.  You should note that Chris's interfaces have been used extensively in production systems without any security issues: there's no reason his approach should be any less secure.  It would, however, be good if InterSystems published their superserver API for third-party use: I am sure Chris would then adopt that instead.

This Go interface has been around for many years and is fully available and supported:

Just to set the record straight: we've had a GoLang adapter for Cache/IRIS available since 2019:

Also for Node.js and Bun.js, PHP, Ruby and others.  Check Chris's repository on Github.
