Dear Richard,
Although I have not seen the phenomenon described that frequently in
contemporary analysis I use this device (which I have always referred to as
a scaling procedure) frequently in my own music. I have also observed it in
the music of my contemporaries - notably Magnus Lindberg.
As a co-developer of the Symbolic Composer software we created a function
called symbol-scale which enables rescaling of pitch material by percentage
or between give pitch parameters. This function has present within the
specification since 1992. This function features regularly (as an
I-function) in the scores of my Six Concertos, the background of which is
documented is some detail here:

For an instance you can examine in a single work, download the SCOM code
annotation for the score 'After Hindemith' for piano trio.

I hope this helps.
