That last statement ("if we want to discourage....") seems a stretch. 
Precisely one of the values of a textual format is its accessibility for 
all sort of purposes that involve reading the file. Why would you want 
to take that away?

In already compiled JARs, has rampant editing of MANIFEST.MF files ever 
been a problem in the history of Java? How about for the history of 
OSGi? That seems evidence enough that developers are already 
appropriately disinclined to directly edit files of this ilk because of 
the zipped archive that typically carries this kind of data.
