That's also true.

Usually we try to keep it working, i.e. we try to fix *new* bugs.
But we normally stop trying to improve it, so there's no need to fix
bugs that existed long before.

The code you changed fixed just one of hundreds of similar cases all
over the Elisp code base. Basically any use of forward-line,
beginning-of-line, line-end-position, ... needs to be adjusted to
account for selective-display=t.
This need to change every package to accommodate the possible use of
selective-display=t is one of the main reasons why we don't want to
support it any more, i.e. why we want to declare it obsolete.
