I don't see anything wrong with teaching or learning them, but I can
also see how it's much more important for a commercial pilot flying
high performance aircraft than for a spam can driver.

If you're holding at 210 kts (and maybe limited to less than standard
rate turns by your FD), you're going to eat up a lot of sky. The
correct entry may be the only thing keeping you from blowing out of
the protected area. This is much less likely to be an issue at 90
kts.
