Actually, it did. You could dynamically load a script, or external
script file, by opening a layer, write to it, and close the layer.

I have never seen, nor do I remember, that ever being a problem. But all
it would take is an escape in the <\/script> tag to cure that problem.
Why make it harder than it has to be?

That's not good advice to give. Always use the type attribute and let
the browser deal with it how it wants. Do not produce invalid code just
because one ancient browser ignores it.
