That's a myth not really backed up by the code.

Another myth.

It's how things are.  Whether they are encouraging or not depends on
what you intend to do about that.  If you want to change/improve it,
come aboard, study the code and its callers, and then redesign and
reimplement it.

Seriously, what did you expect from a 35-year old program that gives
its users an unprecedented amount of power to tweak its workings?  You
can call terminals "quirky" all you want, but they are all still very
much with us, and we must support them, the newer ones, the mouse, you
name it -- all in the same event queue, because that's how Lisp
programs expect to see the input events.
