It sounds like a solution that looks for a problem to me.

What exactly is the problem with the very long lines you see now?
Emacs has several display-related capabilities to allow you both bring
the hidden parts into view and disregard them, depending on your
needs.  I don't see why we need to add a pretty-printing feature,
which would definitely make the buffer have more lines, and then on
top of that add a customization option to selectively disable the
pretty-printing.  It's a complicated solution (and likely will become
even more so once we implement it) for a problem that I fail to see in
practice.
