We thought that the switch to workspace builds in https://bugs.webkit.org/show_bug.cgi?id=241298 would fix the issue where every build would be effectively a world build. It has not! Something else must be different between the XCBuild queue I've been using for testing, and the main build queues.
For example: the build for https://commits.webkit.org/251508@main, which is an entirely non-code change, finished in 1:27 on the testing XCBuild queue <https://build.webkit.org/#/builders/463/builds/3154> but took 43:15 on one of the main post-commit queues <https://build.webkit.org/#/builders/29/builds/13435>.
After talking with Jonathan, I'm guessing that Tools/CISupport/built-product-archive is the issue, because it deletes built products out of ./WebKitBuild during normal operation.
