By removing this, we can no longer make a compliant implementation since we
disallow 'immersive-vr'.

Do you know when this removal was discussed? We don't want to be
automatically opted into VR experiences because they look out of place in
an AR headset.

I suspect that that won't be possible. Looking at CSS, there's so much
overhead in updating specs (authors need to be reponsive, group has to
vote, W3C needs publish, etc) that the style and tooling changes over time.
