Join Hyper-V host to guest domain?

According to the Microsoft article below, Microsoft recommends joining the Hyper-V host (with GUI) to the same domain as the guest VM's.  If I am running 1 or 2 guest VM's on the Hyper-V host, is that the recommended method?  If not, why?

Many thanks.

Thank you Phillip,
What you wrote makes sense but since I read a lot about putting the host on the domain are there any real advantages to putting the host on the domain?
What about backing up the host?  I will be using ShadowProtect and ImageManager to backup the guest VM's to a BDR and then to the Cloud, BUT what about the HOST?  Should it even be backed up or should I use a simpler solution such as Windows Backup to an onsite USB drive?
Thanks.

Simplicity of management. RSAT can be set up to connect to the Hyper-V host via any domain joined system running as a Standard User. Right click, Run As Admin, and Credential then good to go.

Make sure to keep a record of the local admin account. If there is a chicken and the egg event that could be the only way in to the host.

We don't back up the host.

Phillip, Thanks for your replies.  I'm weighing the (convenience) advantages of putting the host on the domain versus the disadvantages you mentioned.  Is the only advantage of keeping the host independent and off the domain in protecting it from a malware infection?  Are there other advantages in performance, etc.?  If not, is the protection from malware enough of an advantage, since you're not even backing up the host, and I assume you can rebuild the host fairly quickly/easily?
Thanks.
