More or less the same as in post #13, but using a new filter (instead of an action):

Code:

function generate_sitemap() {
    $nositemap = exec_filter('replace-sitemap',FALSE); // a plugin could return TRUE here
    if ($nositemap) return TRUE;
    
    // ... GS code for generating the sitemap

Opinions? Better than a GSNOSITEMAP gsconfig setting as I also suggested?

Instead of all that, maybe just use a global for the sitemap itself (xml or array or object), before creating it, call the hook, if after the hook the global is no longer empty then something already made a sitemap for us so we exit.

Also i think exec_action uses call_user_func which is anonymous and will never get the return value, actually since exec action loops its not possible to even have a return, or else it would break the loop.
