This idea became an intellectual design curiosity to design and build a functional JFET voltage-tuned Wien bridge oscillator. The Wien bridge is essentially a series-shunt RC network that results in ...

I did a quick simulation of just a single RC low-pass filter and measured the amplitude response when the phase shift was 60°. I was surprised that it was -6 dB, a very convenient value.
