Now opinion time:
I think sailing at all in a squall is bad mojo - a down burst can hit from any direction at any time. You can literally be hove to one minute and beam on the next second (followed by broached, then poached). You can't heave to on most boats adequately in the varying wind speeds of a squall - most boats require fine tuning the sail/rudder trim.
You have every right to your opinion. I happen to disagree with you with respect to my boat. With three reefs in the main and a staysail up Auspicious is very controllable in high wind. Weather helm does build up, but even in 60 kts gusting higher she hasn't rounded up.
On the other hand, in my old Catalina Capri 22 I would certainly drop all sail and run for cover.
