I can confirm that review process got much worse from the developer perspective.
Same situation as above: due to new CSP regulations we must have re-uploaded couple of extensions with modified configuration. The codebase hasn’t change a bit. Uploaded code was not minified in any way, it was only bundled my webpack (which used to be totaly allowed) but alongside bundled files we always attach map files to make review easier.
And in both cases we were asked to provide source code of the extension, even though the code hasn’t changed a bit, and was successfuly reviewed in January.
