Wouldn't it be better to then make the parameter optional with default
value as None, I have two reasons:
1. I see the two parameter form littered around in aa.py *hides*
2. The function has built in handling for cases when the options are not
present and sort of makes sense to have an option free serialiser with a
default
3. The None there looks absolutely meaningless and confusing (to me and
explains why I above said two reasonsand not 3)

force storing in profile_dir you mean?
