But how does user know if there are area landmarks defined by the
designer of that page in the first place?

The first rule of Accessibility with Human Computer Interface Design is
to facilitate user's anticipation about the structure of the page.

For example Imagine if there is a large page and I want to know if there
are headings.  Now, i press h and i wait for a few secons or more
depending on the size of the page, just to hear "wrapping to top, no
more headings found ".

Had I known that the page has 0 headings, I won't try the command in the
first place which any ways gave orca a performance hit.

Same thing will apply for landmarks and I believe every one agrees that
on a big page, orca will take a performance hit and would slow down the
system and overall response because orca will scann the entire page for
the structural element which the user are trying to search.

happy hacking.
