conditional debug

Describe the feature you'd love to see

I'd like to do something like if (myDevCondition) initDebug();, so I can have different output files where that condition is either true or false. I know I could do require('preact/debug'), but that wouldn't translate to pure esm, as it would mean I'd need to process the if out of the code, which currently isn't yet possible.

Maybe initDebug from preact/debug/src/debug.js could be exposed somehow?

Additional context (optional)

In my libraries I'm using preact as a dependency, so people don't necessarily import it themselves.

closest issue I find is https://github.com/preactjs/preact/issues/1746 which suggests to "just use require", which probably works on pages, but not really on libraries
