This would be a good thing in theory, but it would require a major version bump. Maybe we can include that when we need to break backwards compatibility anyway

Makes sense.

Would it be possible to make a prerelease of some sort which includes this? Or is it too far in time?

Another suggestion:
Can me make a change where we make a global switch to change how errors are thrown?

Something like

const initSqlJs = require('sql.js');
initSqlJs.throwAsErrors = true;

Definitely a good way to incorporate the behaviour keeping it optional and eventually making it the default whenever a major bump is planned.
