There are already unintended consequences namely that the type is reseted if the value of the attribute is changed (meaning set anew, even with the old value).
This is not what you'd want if you change the value of an ID.
My concern was more of correctness of the current implementation than having new convenience methods (which actually aren't convenient because one would have to first query the type of the attribute to change it's value).
Another point I dislike at the current implementation is the creation of a new object on each change.

IMHO convenience methods should have a real benefit and one should rather try to reduce them than to increase them in number.
