In fact, he shares it. You just think that he thinks that ex mode is a
quasimode, which it isn't, and which he doesn't.

That's the difference that matters. You can never *not* know whether you
are in a quasimode or not.
Also, composition, or complexity of the underlying model. Consider ex
mode. How do you edit text in it? You don't have normal mode to help
you, it only operates on "real" buffers, and you certainly don't have
ex mode available. If "ex mode" were just a command buffer, you could
use every piece of functionality your editor provided, maybe even open
another command buffer operating on the current one.
Or simply, as Connor put it, "all we're doing is editing text."

So you got used to the workaround and don't require a solution to the
underlying problem. Great, more power to you! That doesn't mean anyone
else should, or should have to.
That's what quasimodes provide: You don't have to get used to exiting
them, because you can't forget to let go of the trigger.
