I wouldn't make a decision to "feather or not feather." Sometimes it adds a subtle drive that feels great and sometimes it is inappropriate. Let the song, section or even soloist decide.
If the tune is being played sparse and free in a small combo you probably just want the bass drum as another voice to add in here and there. On the other hand, adding a light feather right after a two measure break leading into a driving solo feels great on the right tune.
As Bart mentioned, let your ears decide
