The OP was asking about ways to see both ends of a long construct, stating
that
highlighting was not helping much when one end does not show in the same
window.

I suggested a technique the OP could use (and that I have used often):
activating the follow-mode and splitting the window in 2 or more vertical
windows.
With point on the '(' in the left window you might be able to see the end
paren
inside one of the window to the right (with both being highlighted).
It provides more vertical space to see the entire construct.
It might or might not be enough, but it's more than only 1 window.

I was trying to address the OP last question,
   "Are there future possibilities or capabilities to address this ?",
by explaining a technique that can be used now.

The follow-mode has been available for a while (docs states >= 19.31).
It does not require using the option ‘show-paren-context-when-offscreen’,
only available
on  Emacs >= 29.1.

Correct.  You don't need Lispy. paren highlighting is available out of the
box.
I mentioned it, because of a previous post.
