No. Your assumption of feedback messages present only with stateful
pages is wrong. A stateless page can register feedback message, even a
flash message (feedback message not associated with a page).

I have no idea how did you come to that conclusion. Session is the
place to store state shared between pages (except for simple object
passing from page to page, you can use page constructor for it).

Are you page stateless? If not, you don't have to worry about it. Also
if you don't want new page instance created on reload yet you want the
url to be bookmarkable, mount the page using HybridUrlCodingStrategy.
