Using the Backpack API after the latest release and making a /ws/pages/all request, the start page is not returned in the list of pages.

You’re right!

I’ve been asking for a while if there’s a way I can determine the Home/start page from the list. Maybe there’s another way of accessing this page now.

I do it by finding the page with the lowest ID.

It looks like this has been (kind of) fixed. The homepage is now at the bottom of the list. It’s not in it’s correct position based on the ordering by page name, but at least it’s there now.
