How so?  In fact, it completely separates the feature from whatever carrier is used.

I really dislike this PR as it brings, in my opinion, unnecessary weight and code to the objects used everywhere for what seems to be a small side feature.  I am ok with adding support to it, just not the way this PR does.

I would say `AttachedProperty.of()` or something like that way is probably the least intrusive solution that I would support.
