Nonsense.  In EAGLE you can't delete or add PADs to a package that is  
in use, but you can certainly change the pad size and placement.   
(You still have to do this in the library, but you don't need to  
create a whole new package.)

Since eagle copies all the package/device info into the schematic,  
you can also export the library of used components from a published  
schematic, then modify and update from that new library, to avoid  
having to change the original (why it isn't an easy step from there  
to being able to edit the package within the particular project, I'm  
not sure...)
