It just didn't seem fully baked yet, the 'do' subcommand works fine while the 'bwrap' alias has this problem: `bash: cannot set terminal process group (1): Not a tty`. When executing 'bash -li'. Also the EROFS feature of 'do' should probably be included in 'bwrap', it can be useful. Include overlay options.
Also some things you can do to make gvisor better are Wayland passthrough, vulkan support (or virtio native context). Being able to get gvisor to populate a network interface inside itself through a 'passt' (or 'containers/gvisor-tap-vsock') socket on the host would also be ergonomic. All of those are available on 'muvm' (based on libkrun) which if you have the time to set up is the next step in DIY sandboxing of graphical apps as well. See: <https://git.clan.lol/clan/munix>
