Metadata is locked at time of submission, if it’s changed since your submission then that’s cause for concern, otherwise it’s expected!

Not sure what the expected behavior here is, to my knowledge this was never officially supported (I’m new on this area though, so grain of salt). I’d strongly, strongly recommend pushing your apps through the review process here and maintain at least a version of backwards compatibility as you go through the review process.
