Somewhere in this thread, the 8038's more recent spawn was mentioned.
Obviously, it will work over that full range, but I'm suspicious about
how good it will be at radio frequencies, as I would about any RC
oscillator. It seems a stretch to expect it to work as well at 12MHz
as at 10KHz.

I agree. But on the other hand if you controll this 8038 with another PLL
synthesizer, i think the overall performance should be ok from 10 kHz to 12
MHz. I think that is the way how most of "pro stuff" works.
