> Put another way - if you are not part of the invited group, and you submit an issue, but do so poorly, or without a clear Proof-of-Concept, and concise description, you can reasonably expect to hear no response from Apple, with no grounds to complain that they ignored you. But, at the same time, if you have a clear exploit, well documented, with impact and proof-of-concept, then their is still an avenue to submit it to Apple, but it's up to Apple to decide how they wish to prioritize.

Thanks, that does make a lot of sense.

My main exposure to bug bounty programs has been through the blog post of submitters, that don't give much insight to the resources/support that e.g. Apple would need to give.
