Sometimes, but not always. We deleted the ones that were not, and finished the ones that were.

As far as noticing these by hand: my current project is about 600,000 lines of hand-written code, not including several libraries we also author and use in it, nor other projects I'm also heavily involved in. I haven't even looked at all the code yet, much less do so on any regular cadence. Forgetting is something you plan on and address up-front, not something you just let happen.
