Why do I find ^L in elisp code?

[Christopher Dimech <dimech@gmx.com>]

Is it still useful in new code? 

The Form Feed is hard to type.  Most text editors do not provide easy ways to type it.
Could emacs cease using invisible glyphs as they could be are confusing and hard to read
and type?  Sometimes I see an ASCII art box.

Regards
Christopher
