First of all: I don't think this is suitable for trivial. The actual
code change might be small, but the change in behaviour is important and
needs discussion.

Yes, I'm concerned that making it conditional might be a bit surprising.
I'd like to hear some more opinions before applying this.

Also, should we consider making some more rarely used image formats
modules even if they don't pull in external dependencies?
