preference is not to add extra dependancies when they are not absolutely necessary - can you add a debug helper script (which does console logs) instead of a 3rd party lib?

yeh I agree, can't say I've seen this much in OSS. Maybe if it accepted debug as an optional prop that would be better. Any examples of other libraries solving this problem @danielbush?

Probably the size is less than 7k when bundled and minified down a bit more but I get the point.

Yeh, it's not as common in the browser. I've used it in a complex spa where I can selectively enable debugging to see what the system is doing, eg localStorage.debug='containers*,system1,foo,bar' etc. and it gives nice coloured output and might complement a similar use of debug in the consumer of this component to allow us to trace failed variant activation.

However, given the situation, maybe we just JSON.parse localStorage.debugReactExperimentify and if truthy/falsey behave accordingly; if it fails, reset it to falsey and warn the user?
Feels more straightforward to me than passing in debug.
