The competitive spirit between temperaments is unfortunate. Clearly, there are merits to both Standard and Classical temperaments, depending on what music is played and who is doing the playing. Not everyone's taste is alike, just as all music is not alike. Equal Temperament works better on some music than does Well Temperament. Well Temperament works better on some music than Standard Equal Temperament.
It may be that in the next decade or so you will see a change in the temperament of piano technicians.
Recently I went to the Piano Technicians Guild seminar put on by the Madison chapter on historical tunings. The first part of the program was a lecture / demonstration by Owen Jorgensen, with whom I'm sure many are familiar. Owen had two pianofortes, three verticals and two Mason & Hamlin grands, all tuned to differing temperaments, however this time his lecture had a little different and quite unexpected twist.
