Why so?

- Very irritating to setup on mobile clients (iOS profiles are not a good solution)

- Usually hosted on shared VPSs where IP reputation is decimated (wonder how this will be affected by pure IPv6 hosts)

- Patching is often manual and forgotten about (n = 1)

- Backups are often an afterthought
