Yes.

No. The native line-number display is implemented inside the low
level of the display code, and I don't want to call to Lisp from
there. If nothing else, it will slow down redisplay when line numbers
are used, whereas avoiding that slowdown was an explicit goal of
developing native line-number display.
Why aren't the existing faces enough? And if they aren't enough, why
cannot you use line-number-mode?
