It depends on what level of control/customisation you have over the guest.

For most cases, there's no point I can see. However, there will be 
cases where "appliances" are being employed where it may be required. 
The sort of situation I can think of might be where you buy am 
appliance which comes as a complete system - "insert [ CD | USB Stick 
], switch on, wait while it installs". In that situation, the vendor 
may simply only support unmodified bare-metal installs.
Running it as a PV guest will be right out, running it as an HV guest 
you will probably get away with - but not necessarily. Slightly 
different these days now that standard kernels tend to have the Xen 
stuff - so you could probably manage to run the appliance as a PV 
guest without having to use a different kernel.
As an aside, at work we have some customers using a particular 
package (on Windows). This isn't supplied as a disk, you have to call 
up the vendors, give them remote access to your server, and they will 
install and configure it. They will not work with a virtual machine - 
not even using Microsoft's Hyper-V. I think for one customers, we let 
them install it, then imaged the machine into a VM.
