Hmm, if the line youʼre going to is visible, why would
you need goto-line to show line numbers? For that matter, why not just
move to the line using other motion commands?

And if itʼs not visible, what does showing line numbers for the lines
that are visible get you?

You'd have to add some interactive 'scroll window to show target line'
functionality, I think.
