Yeah, no. Every MVP I've ever seen has been riddled with problems. Hell, even publicly launched projects are a mess most of the times. How many social networks we've had in the past 5 years that were pwned right after launch? I remember at least 4 or 5 very public failures (firebase tokens, client-side apis and so on). Those are just the most public ones.
Everyone wants to pretend that the software used to be better, but the reality is that MVPs and sometimes even public launches were always a house of cards.
You are pointing to the same low code/no code prototypes that I am, but you keep calling them MVPs for some reason. There's no "used to be better" here, there is good and bad software full stop.
