Is it possible to output a warning "No Fetch API detected."?

I am studying sentry/browser code.

Initially, logger.enabled is set to false.

In the initAndBind function of sentry/core, logger.enable() is called, and the logger is enabled from then on.

However, logger.warn('No Fetch API detected. The Sentry SDK requires a Fetch API compatible environment to send events. Please add a Fetch API polyfill.',); exists above the initAndBind function.

Is it possible to output a warning "No Fetch API detected."?

We do not officially support any environments where fetch is not supported. Why would you need/want such a warning? Do you expect this to not be supported somewhere? I was actually thinking about removing this warning all together 🤔 (as this will trigger a warning/error/log anyhow once the SDK tries to send something to sentry and encounters fetch not existing)

I was just studying your code and found that line wasn't doing anything.

[mydea]

you are right! We'll remove this line altogether probably.
