So one arrives, utilizing a perfectly valid ticket, at Blackfriars.
But, one cannot exit on the South Bank because it is managed by
another operator.
No, you definitely can arrive by tube and exit on the south bank via
the NR station. The only time you'll pay an avoidable fare is if you
walk in off the street AND cross the bridge AND exit without making a
rail or tube journey. This is exactly what happens if you enter and
exit anywhere else, it is NOT specific to Blackfriars at all.
For example using Earls Court station as a short cut from Warwick Road
to Earls Court Road.
Though given both Trebovir and Penywern Roads are parallel to the
station (one on each side) I wouldn't really call it a 'short cut'.
This is what is explained (badly)
No change there then 
by FCC on their website.
