Right. It is entirely possible that if you did a temperature test in an environmental chamber, you would find that you could get a better tempco by adjusting oven set point to have a slight offset from the turnover. In this regime, the crystal drift would cancel out the tempco of the electronics. This all depends on the crystal tempco, the electronics tempco, and the respective thermal gains to the crystal and the electronics. But there will be an adjustment giving zero tempco (at least around a single ambient temperature). My old boss at Agilent used to call this sort of thing a "hero experiment", which he used as a pejorative term.
