Only when they claim an impossibly low distortion.
But indeed, one could claim that a sine oscillator
never produces a sinewave.

That varco will have a drift that is no
way able to keep up with the 43 decimal digits
of your desired resolution.

I think your wish has to do with the effect
that an immediate frequency change produces
a very objectionable auditory effect, not
unlike a click. Old electronic organs suffered
from this. Gating an oscillator has a similar
problem, as does using extremely steep filters.
