Even 24 years later: some folks are still out there, interested in burning in their cables.
Of course: some, less patient than others.
The Ayre CD has Pink, White and Brown Noise tracks, that when set to play repeatedly, should provide a (somewhat) faster burn than random music, containing more full frequency spectrums.
The full frequency sweeps on the disc, can't hurt either.
I agree: critical listening, when changes are made to one's system, is educational and, "good training".
Still: many just want to get on with their better sound, quickly as possible.
I suppose: why there's a market for cable burn devices*
