The main downside of using a switch in your DRBD interlink is that you add another component that can - and at the worst possible time will - fail. If using a switched network use it with two network cards, two switches and Active/passive bonding. Otherwise you have the switch as single point of failure.

It's more a case of "common sense agrees with general recommendations agrees with general anxiety" ;-) I'ts also that I'm fairly certain that if you do use a switched network for you DRBD links, it is unlikely to be dedicated (because then it would be almost trivial to remove the switch from this piece of your setup). Again, I've been in situations where you cannot have a dedicated link, and I sympathize, but it's a painful choice and I encourage everyone to refrain from it. I cannot comment on the sense (or lack thereof) in switching your dedicated links. Your point appears valid.
