It’s hard to have this conversation given the countless definitions of “Agile” but I think the majority of what I’ve experienced does not help with the concerns you raise.

Often the desire for Agile comes from not knowing how to manage a project and reaching for the popular thing that people think will magically solve their lack of expertise.
