Yes, you already said that, it wasn't convincing the first time.  The
documentation exists for a reason.

There are several features that show the current line, all of them
optional.  I see no reason to make that on by default now, and in any
case this is a separate issue.  IOW, if you are lobbying for making
the line-number-current face be distinct by default for this reason,
you will have first to convince that making the current line stand out
by default is a good idea.  (And the place to make that argument is
not here.)
