In the middle of a line FF would need to be whitespace which would mean
you have to decide how to display it, etc.
Treated as a line-end it is discarded as the file is read, and there are
no further repercussions as the FF is not part of what gets interpreted.
There would be the side effect that 5!:5 would not recover the FF. But
if the FF is useful to editors and doesn't hurt us, I can see allowing it.

Is it used only when alone on a line? Things get messier when it is allowed

FF is actually pretty commonly used in source code... I use it all the time

It's actually used as part of the GNU C coding standard, according to
wikipedia (pretty sure that's where I picked it up...)

In linux jconsole input ctrl+l, is not treated as LF. Instead it scrolls

I think you will find that ctrl+l will behave differently on many
different
hosts, terminal managers, J front ends, etc. I think making it behave in
a
useful way and the same way in all cases is not possible. And including
it
is a script introduces a whole new level of complication.
Before changing the JE, the use case should be studied and probably
revisited.
And it is unlikely to be consistent with other languages.

Yes.
