Based on these news, will there be taken steps to support this new format? It looks very promising 
This has been asked before. In short: we’re keeping an eye on it, but there needs to be movement on its adoption first.

Any chance of an updated Vero that has support for AV1? AV1 is getting serious traction.
It’s something that we continue to assess, but we don’t have any news at this time.
This would be a good feature. I have some videos from YouTube in AV1 and it would be great to be able to play them with Vero 4K+ which seems to handle anything else well. Is the support for existing devices via software decoding even a possibility?
Software decoding, even using dav1d is very computationally expensive.
720p would probably be a go, but higher resolutions won’t be possible on current hardware.
In my opinion it is useless to add the av1 codec to OSMC without proper hardware acceleration. It would be only a waste of time!
Cheers!
Youtube is starting to use AV1 (av01). Additionally YouTube DL grabs these by default as they’re identified as the best quality option, so I’ve got some videos I can’t play on my Vero without redownloading with some additional args to grab different quality

And also if you just execute youtube-dl on the id without parameters you get the 2160p vp9 version not the av01 one.
Ah I get AV1 versions by default because I’m using youtube-dlc:
$ youtube-dlc 'http://www.youtube.com/watch?v=SIgznB0-ICo' --get-format
401 - 3840x2160 (2160p)+251 - audio only (tiny)
$ youtube-dl 'http://www.youtube.com/watch?v=SIgznB0-ICo' --get-format
313 - 3840x2160 (2160p)+140 - audio only (tiny)
For others who might run into this in the future. I was able to fix to ignore av01 format with a format string:
$ youtube-dlc 'http://www.youtube.com/watch?v=SIgznB0-ICo' --get-format -f 'bestvideo[vcodec!^=av01]+bestaudio/best'
313 - 3840x2160 (2160p)+251 - audio only (tiny)bump for a new device with support and also hdmi 2.1
