I don't think real requirements are known and understood in general.
For example, consider a team that has been maintaining the system for a long time. Most or all of the people that has initially created the system have moved on to other positions or companies. Many of the people who stuck with the team did so for reasons of being experts but are also unable or unwilling to communicate well (for example, because they see the value in preserving their position of being one of the few people with expertise).
In a team like that, they might have good memory of things they have worked on recently, but not necessarily things that are working and the users take for granted. Users do not typically spend much time reaffirming the features that are working well.
One of the challenges of working with stakeholders is that close to 100% of the communication tends to be on things that are not working or are missing or they want to get done. As a developer or manager of the team, you need to find some way of answering the question "am I doing well?". Because users are of course unhappy with how the application works, but to understand levels of unhappiness you need to find some other reference (working for some other projects).
I was yesterday in a meeting with developers where they complained about how manual our deployment system is.
Our deployment system requires them to press a button to deploy a version of the application to the environment. Yes, log in and press a button.
I explained, that I worked in the past for teams that had hundred page manuals on how to compile and deploy the software and that manual would be compiled again and again for each release and the process would take from couple of days to a whole quarter.
So you need to have some perspective to be able to judge that kind of feedback.
