Great discussion! I don't have any strong opinions just yet.

But when you wrote this:

It reminded me that that there is such thing as a .digrc file, that 
perhaps not all of the readers are familiar with.

Mine has this content:

+bufsize=1232
+dnssec
+nocrypto
+multi
-t AAAA

It serves me well, mostly. Sometimes it bites me as well.

In general I'm happy with it.

Best regards,
