I've seen that happen a thousand times, yes. (Slightly exaggerating, but still.)
I guess we'll just have to wait until people get used to the idea that the Web is an interactive document format, not a replacement for the GUI. I'm hoping the modern SPA trends pass into the void like the Macromedia Flash UI trends did.
At many companies anything is a SPA now, which seems like the worst example of cargo cult mentality. It takes twice as long to develop, but with all these people who only know JavaScript you have to give them something to do.
