"The Compensator valve was necessary to allow for the LONG STROKE SMALL BORE BTV master cylinder."

Really??. The GM designed/manufactured Delco-Moraine unit debuted in about 1956 and was used in all GM divisions alternately with the BTV. It was almost the identical length/width/height as the BTV AND IT WAS ALSO A LONG STROKE SMALL BORE UNIT. It was not designed "in a rush", it came out 4 years after the BTV. It had a LONG STROKE SMALL DIAMETER but it did not have a compensator valve. THE COMPENSATOR VALVE WAS THEREFORE NOT A NECESSARY
DESIGN ELEMENT.

The look-alike Delco unit was discontinued after about 2 years in 1958. DOES THIS PROVE THAT IT WAS A POOR DESIGN????? Or just time moving on. Three speed transmissions, vent windows........poor designs....
