Great analysis
I agree with most of your points. Those CH 27-70 movements are beautiful. The 5070 and 5970 represent the end of an era, where inward angles were applied to a "mid-range" Patek Philippe movement. There's nothing inherently wrong with industrializing a manufacturing process, in order to offer your luxury goods to a wider audience.
I think much of the disappointment comes from collectors who don't necessarily have a full grasp of what they're buying when they acquire their first Patek. The marketing always leaves much to the imagination. The imagination says, "Patek is the best," which a new collector is likely to interpret as "is made without consideration to cost".
If you've been collecting for a long enough time, the expectations are closer to reality. Very few beautiful objects are made without consideration to cost.
You can assess the technical advancements going from the CH27-70 to the CH 29-535 and decide that these technical improvements outweigh the loss of a few inward angles that don't serve a functional purpose in modern watchmaking. If you feel otherwise, you'll gravitate towards independent brands that hand finish. This is different from buying the watch first, becoming a brand evangelist, then being surprised by the fact that there is cost engineering in the watch.
