This is a matter of taste and I don't think we will ever have a
consensus here.

For interactive use, I remind people dig reads ~/.digrc at startup
and this is a good place to put the options you like.

% cat ~/.digrc
+bufsize=4096
+dnssec
+multi

For script use, it seems to me that the good practice is to be
explicit (put all the options you rely on). It may be a long list but
you type it only once, and it makes your script both more robust and
better documented.
