Many mixup rogue CA with MITM.
Private CA rarely mitigates either since
a) full stock of public roots usually still installed and active
b) fingerprints / certs still rarely pinned down
c) possible MITM's exist at many layers

Wrapping / initializing things with PSK's is different situation,
though only if exchanged out of band, and such auth / psk
modes are hard enabled.
