While this will be preference, is it recommended to add a class for annotation?
(i.e. add a class which is not used by any selector just for comment). WDYT?

It's fine to remove class. Sorry for confusion. My original idea was to make the
difference between paper-button and button clear.
How about adding explicit HTML comment that explains why we can not use paper
button here?

Done.
