None of those are concrete problems, just "it may cause problems" without listing the actual problems.

A short list of the big ones would be very helpful when deciding it's worth it - the listed alternative (run another instance in a VM) would have some very concrete downsides (mostly increased admin workload and potential confusion). Having something to weigh that against would make deciding a lot easier.
