This isn't very extensible.  You're missing some options, and if we
ever want to add more, we have to add more combination options as
well.

Better is to define a dictionary with keys of "transform" and "clip"
(+more?), whose values are bools.  Like you say, not passing the
dictionary is taken to mean "save everything".
