[sdiy] Sine-wave VCOs?

[Metrophage]

I can't help but notice that practically every synth circuit I see
which has a sine output was achieved by shaping another wave, typically
the triangle. Is it really so hard to make sine VCOs, or are they just
not desired? Of course, many schematics I have seen are just "function
generators", probably precise but with no voltage control. How does a
keyboard tracking VCF which self-resonates compare? I am not so much
into subtractive synthesis, but it seems to me that filters might
suggest ways to build sine VCOs
