Actually, and in an odd sense, it does.
If you go into the library of that part, and change the pad diameter,
then save the library, do a library update, then it does.
That's for all instances of that part, though.
If you want to preserve your own libraries, then you must copy a part
from the supplied libraries to your own, change that part, and then
replace that part (every instance) with your own part. Then you have
control over it regardless of what you (or they) do with the eagle
libraries.
Royal pain, but only needs to be done once.
Oh, and you might look at the design rules and change them. Doing so
can change the size of a pad for a via, for instance, globally. Never
tried it with parts, though.
