Are there any plans to support mapping of individual files with vctl? Or is it already supported with latest 12-release?

Documentation says it's not, but documentation page says it's updated Aug 26, 2020, yet does not mention the support for declaring a mount Read-Only, yet in a blog entry found here (https://www.definit.co.uk/2021/09/replacing-docker-desktop-with-vmware-fusion-or-workstation/) is using it. So I'm thinking maybe documentation is just not updated with the details introduced by later Fusion releases?

I'm on Fusion 11.5.7, and considering version 13 seems to be due any time now, it seems "risky" to update/upgrade just to test that detail.
