What about using OpenThread with Espruino

Is anyone in touch with this solution?

They offer different implementation on nRF devices eg as bare metal or as co device via spi slave or uart.

The boarder router is available for raspberry pi3/4 and beagle bone black.

Espruino devices could access OpenThread network via a co device like esp's for wifi and wiznet for ethernet.

Yes, I'd been wondering about that. It's definitely a possibility.

I don't think it works on nRF52832, just the newer breed of nRF chips (like 52840?), so it wouldn't be any use for Espruino devices that are out there right now though.

Also, I could be wrong but I think Nordic's implementation of OpenThread sits on top of Zephyr - so porting Espruino would be a similar task to porting to an whole new platform (eg you'd need to redo I2c/SPI/Serial/etc).

maybe not, it is not clear but the release noted mentions sdk16
https://infocenter.nordicsemi.com/topic/sdk_tz_v4.1.0/index.html?cp=7_3_0

*** Changes to nRF5 SDK v16.0.0
*******************************
The following changes to the SDK v16.0.0 have been made in the nRF5 SDK for Thread and Zigbee v4.0.0

I guess softdevice has some radio coexistance API so you can schedule another protocol packets between BLE packets

EDIT: oh yes

Supported SoftDevices for multiprotocol support:
- S140 v7.0.1
