I am not sure I understand your question. Maybe a summary of the discussed
terms will help:

* character protruding (or margin kerning): doesn't have anything to do
  with expanded fonts -- it can be applied to any font

* expanded font: is a font that has slightly changed width. The font file
  will be embedded for each instance. 
  
* fonts that have map entry containing "1.2 ExtentFont": the font file is
  embedded for each instance. It's similar to expanded font, except that
  expanded fonts are (usually) generated automatically and by a very small
  amount.
