I was thinking about this approach but the only downside is
physical deployments and non-VMware VMs. I'm not sure if it
is common to install unused packages on system.

Yes, vmtoolsd service is a no-op in all non-VMware environments.
In fact, it will simply exit even if systemd check is not there,
because we do a platform check inside before starting the main
loop.
