Two comments:

 1) display-line-numbers-mode by default behaves the same as
    line-number-mode
 2) display-line-numbers-mode has the display-line-numbers-widen
    option which disregards narrowing, so if you want to follow
    display-line-numbers-mode, you will need to heed that option as
    well

I like this the best.

That sounds wrong to me: there's no real relation between these two,
and having the same command behave differently in two buffers doesn't
sound right to me.
