Ditto
I think it was too different from other cars and to bleed them, you kind of
had to know what circuit went where.  
Once the cars weren't rear engine, the front-rear brake bias was too
different maybe, and the safety advantage was lost as the front brake pulled
you too much one way?
Dunno, they made sense at the time and with antilock systems,  would seem an
excellent idea.
