Assuming that the more compression is applied, the more the RMS amplitude [1] approaches the Peak amplitude [2] of an audio signal,
Why do you assume that ? Let's say I take a signal and divide it by its recent peak volume. The output of [osc~] will stay unchanged. A signal made of plenty of sharp spikes will have a much lower RMS/peak ratio and still be unchanged.
Are you confusing this with waveshaping such as [expr tanh($v1)] ? It may be a special case of compression, but is not what is usually meant by that.
