I know that.

We simply need to adapt the streaming system so it can, 
I already studied that, it's fairly trivial:

* When writing: write UnitName.ComponentName instead of ComponentName.
   A trivial change, which can be done in a backward compatible manner.

* When reading, there are 2 lines that must be changed:
   One in GetClass and one in TReader.FindComponentClass.

* To handle the text format, 2 lines need changing.

So this is not exactly lots of work.

If you read my message correctly, you'll see that I know this. 
Additionally my last sentence tells you why I don't use it...
