I disagree, the organization needs to know that feature came from YOU. I'm very bad at this and I from my experience every time I don't do this some one else swipes in and gets the merit, e.g. my boss bragging they were able to successfully lead the delivery (they didn't even know what the feature was about it until after delivery), a co-worker (who might have helped rolling it out during onduty) etc. Promoting yourself is essential.
