Certainly the club fitting guys are always trying to get us to tee it high and hit it way up there. I personally dont like that as much as taking it around low point but with a 10.5 degree driver.
Thanks to Homer Kelley, the Geometry of Low Point (2-N-0) has become more and more mainstream. The 'best' instructors -- read 'Top 100' in the popular magazines -- more and more make reference to it. Similarly, the Long Drive Guys benefit from its wisdom, i.e., post-Low Point Impact means less Backspin.
So, is Backspin the bad guy?
No.
Per 2-C-0, Backspin is not Compression Leakage; instead, it is a valuable component of Ball Control.
Years ago, Lee Trevino waxed eloquent on this point. Demonstrating, he arched his left wrist into an Impact condition and leaned the clubshaft forward. Said he:
"Give me a club with loft . . . I'll take it off!"
