that would pretty much wreck every RF circuit ever built as nothing would tune correctly
It would certainly be inappropriate for tuned RF circuits to use multi-layer ceramic capacitors (MLCC), which have a huge voltage coefficient of capacitance, as resonating elements. I have always used ceramic capacitors for high-frequency by-pass applications, often placing them in parallel with electrolytic capacitors that provide low-frequency by-pass functions. All the RF circuits I have ever "played" with used either air-variable or slug-tuned single-layer ceramic capacitors as trimmers. If I needed larger values of fixed capacitance for tuning purposes, I used fixed capacitors with mica dielectrics.
I suppose there are paper and plastic dielectric capacitors with sufficient stability, but IIRC the available capacitance values are generally too large for most tuned RF applications... at least above one megahertz or so. I have used these capacitors for tuned audio oscillator and audio filter circuits without problems. I may have used ceramic caps for purposes other than high-frequency by-passing of power supply rails, but I think of that as their main use.
