Feature Request - BLE 5 Mesh

Thanks very much for the clarification that's really interesting and even better than I thought.

It seems like Bluz had a special relationship with Particle to get devices registered in the cloud which might be a limiting factor for any 3rd party (including xenons) solution now?
Or is that still possible -

Am I missing something here? 3rd party devices can be registered on Particle?
does this still apply?

Edit : I realise I was being obtuse with the quote about LoRa, but connecting Argon/Borons to Particle using a LoRa add-on seems like a bit of an overkill - something that would be better suited to say... a xenon?
