I have been QA testing, fixing bugs, and adding new features near full-time for the last seven months.
I have a pretty good idea about what maintenance looks like. Particularly so about the technical aspects of how effective the models are at refactoring or fixing bugs.
Even if I were to accept the argument that users would have entirely different expectations for my app than I do, it hardly changes the fact that I already know I can easily implement large changes in the code base.
Not sure if you're trolling at this point but: the previous comment defined "maintenance" for you: "responding to real usage". The things you list are plainly not that.
"Maintenance" does not mean "development after the first week".
I'm not even sure why I bother discussing on HN, only to always get these comments from people who seem to think they know better than me about the maintainability of my own app.
I did not ask for your opinion.
