No

Either trigrat should distribute over "=" or it
provide the user with a helpful error message:

(%i26) e : sin(3*a) + sin(a+%pi/3) = 0;
(%o26) sin(a+%pi/3)+sin(3*a)=0
(%i27) trigrat(e);
Maxima encountered a Lisp error:
Error in CAR [or a callee]: 1 is not of type LIST.

I think the functions trigsimp and friends distribute
over "=".

    Agreed, trigsimp and friends should distribute over = .
