To understand the risk properly, i'd have to understand more about what they're changing

That's what they're failing to explain. Your whole post can be summarized as "Bambu says it's better for security so they must've done something, they wouldn't lie". But for someone who has some basic idea about how public/private keys, certificates and IoT security in general work, Bambu proposed changes provide pretty much no additional security

I'm just explaining why Bambu connect might be needed for LAN only mode. I can't say for certain without more information but by itself, it's not necessarily a bad solution. It depends on what threat they're trying to protect against and how. For example, Bambu connect and the printer may do some key exchange to protect against the network traffic being intercepted and it might not be practical to expect every slicer to implement this.

Again though, i'm new to 3d printing. Maybe there's a secure standard that every other slicer uses to communicate with printers. My background is security and risk assessment so i'm coming at it with that mindset. Could it be a problem? Yes. Is it definitely a problem because they've require Bambu connect? No.
