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.
"Maintenance" does not mean "development after the first week".
I did not ask for your opinion.
