No, that's exactly how UX research works:

- Users are using X feature a lot. 1) the researcher likes the feature: let's invest time into improving it. Or 2) the researcher dislikes the feature: we need to remove it because it's adding too much friction

- Users are not using feature X a lot. 1) the researcher likes the feature: users aren't discovering this feature, we need to make it more prominent. 2) the researcher dislikes the feature: no-one is using this old, outdated feature, we need to remove it.

(I'm still upset that they removed FTP and RSS support.)
