This is absolutely not the case for me and seems more individual to the person than a general fact. Since as long as I can remember I have added #TODO: notes throughout my code / scripts with comments on what could be improved. Have I fixed all of them? Of course not. Have I fixed or replaced most of them? Yes! These days I have some automation that checks through my code repos and logs issues for any #TODO: comments with the link to the line which helps me keep track of them. It works well. I know of people that aren't interested in fixing their code after the fact - generally in my experience they're either: A) Not motivated / interested in or energised by the idea of optimisation/performance. B) Not "allowed" to work on non-features (by a product owner / managers etc...). C) Simply forget about it due to lack of a tracking system or related exposure.
