I've done some work in this space and there are pros and cons. BLE gets very complicated quickly. The mesh idea itself is nice, since there's no pairing / setup time - your device can be mostly asleep, and it simply powers up, sends a few bytes quickly, and powers down - that's a common industrial sensing use case.

However there are broader issues that are not adequately addressed - onboarding, key management, credential revocation and key rotation and so on.

I've also done some work earlier on 802.15.4 based mesh networks, there are standards for access control, payload encryption, frame integrity and sequential freshness, but delivering complete working solutions still becomes a bespoke offering that needs a fair amount of work to get right.

To see a broad adoption of these mesh standards we need to address the broader engineering, integration, deployment and operational issues.
