Thank you for taking the time to comment on this feature request, which
I hope to see implemented in Emacs.

Could this be implemented without modifying the fundamental concept
in Emacs that a point is a position between two characters?

Here’s an idea: instead of modifying the internal concept where the
cursor is equal to the position between two characters, we could
implement a new mode that displays a "virtual cursor." This mode
would display a cursor representing a specific line/column, rather
than a position between two characters. It would allow the cursor to
be placed at a line/column position, which may not necessarily be
between two characters.
