I agree completely.

Exactly.  I guess my implicit question was, whether we should aim to
make :imagemagick accept 'no' as nil to be consistent with the general
org babel conventions.

As I get it, you would say: no.

(The next question would be whether we live with inconsistency or
whether we should switch the other header arguments backward
incompatibly use t and nil as well...)
