[PVE-User] question regarding quorum/qdevice on raspberry pi for dual-node cluster

hello,

on this page https://pve.proxmox.com/wiki/Raspberry_Pi_as_third_node 
there is told:

"Raspberry Pi as third node - This is only suited for testing or homelab
use. Never use it in a production environment! Simply use a QDevice!""

On https://pve.proxmox.com/wiki/Roadmap  for Proxmox 5.4 there is the
following announcement:

QDevice support via `pvecm`

  * primarily for small 2-node clusters adding a qdevice can help
    mitigate the downside of not being able to reboot one node without
    losing quorum (and thus the ability to make any changes in the
    cluster) ** Can also help in clusters with a larger even number of
    nodes by providing a tie-break vote.
  * Integration into pvecm and PVE stack vastly simplifies adding a
    qdevice (it was possible manually before as well)


my question is why there is  information around which looks like
discouraging rasperry pi as third node for quorum, i.e.  is a raspberry
pi with Qdevice  (
->https://blog.jenningsga.com/proxmox-keeping-quorum-with-qdevices/ )
suitable for production use or not ?

regards
roland
