"and it's already coded we just need to merge it in"

Any manager worth their salt will know that maintaining code is 10x more expensive than building it in the first place, and if it's user-facing code you're even adding an implicit promise that the feature isn't going to be removed again. I strongly doubt the "oh but it would be so hard to build that" argument counts for much.

That said, I've no idea about what kind of place Facebook really is.

Well, it's possible that "move fast and break things" is more than just hot air. :)
