I do own one, owned both the Vero 4k and Vero V and they have been brilliant.
OSMC do very little marketing for some reason and are extremely underrated but their customer service and support has been exceptional, new features and patches roll out regularly and the hardware itself is powerful, silent and has a minimal form factor.
Support for mapping Dolby Vision (DV) to regular HDR was recently added and it works seamlessly for the few DV-only media files I have.
The largest file I have is 4K77 (https://www.thestarwarstrilogy.com/project-4k77/) at about ~80GB with a bitrate that can hit 120mbps during particularly grainy scenes and it works perfectly on both the Vero 4k and V.
The only problem I have is anime encoded as Hi10P which stutters slightly on the Vero V during playback because hardware decoding isn't supported for 10bit H264 (Hi10p and the anime encode scene is unusual like that as 10bit is usually reserved for H265).
A similar language is Joker (https://github.com/candid82/joker), Go based, Clojure syntax. I've been using it for years as a general purpose scripting language and Clojure code linter and formatter - it's exceptional.
It doesn't integrate non-Joker Go code as far as I know.
