Isn't the 2246 inverter design just another variation of the saturable
core oscillator with T2205 designed to saturate before T2204?
Yes that's right. Inductor L2206 limits dI/dt and helps to collapse the voltage across T2205.

Tektronix used that saturable core oscillator technique a lot in their
high voltage inverters and I thought I remembered seeing it in some of
the 7000 series.
I have just a few different 7000 'scope types. You may well be right there. The surprise for me was that control of the dead time in the switching transistor pair with the famous IC was abandoned.
