REPLY:

Since day 1? I don't think so. Scopes which read peak to peak  have
been available since the stone age, but meters which will read true
RMS of a non-sine waveform have not, and I suspect are still rare in
most ham shacks even today. 

But it really doesn't matter much IF you specify which you mean. Just
saying "1% ripple" with no qualifiers leads to confusion.
