An excellent point, and something I've never paid attention to - just
blindly following the myth. I typically worry if I forget to lock the
PF in while my machine warms up. I plan to worry no more!
Some other things that may qualify for myths but need proof:
Funny tamping and packing schemes (that tend to get named after
people) like the "Stockfleths maneuver" and the "Staub Tamp" (not to
disparage those who came up with the ideas and got their names
associated with them). Once I got a good grinder, I've found that
the less I fiddle around with what's in the basket, the better the
shot. I just level (sometimes finger, sometimes the back of a butter
knife if my hands are wet). and do a straight level tamp. Other
sillly steps just give me a far greater chance of channeling.
I also believe that the theory that conical grinders are better
because they heat the beans less is a myth. (I think they might be
better for other reasons). I don't think there is enough time to
transfer much heat to do damage to the grinds, except in a grinder
that might be running continuously (in which case you have someone
pre-grinding and don't want shots from them anyway).
(of course I only have observational data to back up my claims. I
prefer to enjoy the few shots I drink a day rather than analyze them).
What other myths can we bust?
