I'm with you on this one:  always hated Sec and Csc (and never 
understood the backward naming of these functions -- why isn't Sec = 
1/Sin and Csc = 1/Cos?)

So, I'd like the various Simplifiy and XxxToYyy functions in Mathematica to 
always give precedence to Sin and Cos by default, and avoid using Sec 
and Csc whenever possible, even if this produces some "1 overs" in the 
output expression.

But I suspect trying to implement this at this point would require more 
complexity than it would be worth.
