The Max 9 has been in service since 2018 though, I think if it was a design issue it would have occurred before now. This seems like a Manufacturing QA “escape” to me. Some bolt was either not installed properly or not tightened to the proper spec, QA did not catch it

That's a bit of a leap. If the bolts are e.g. too soft and have worn out in use, that would be a design issue that would only show up after a period of use.
