In your opinion, perhaps. These faces are there since 5 years ago,
and I don't recall anyone complaining.

They need highlighting to stand out against the unchanged lines.
Since most tty's don't have too many colors, they cannot make use of
the technique similar to what we do on X, which is to dim the context
lines by using light-grey colors for them.

I don't think this is a good idea to make such a change. Certainly
not now, before a release. Haven't we already seen enough trouble
from this comment-delimiter face innovation?
Anyway, the results look IMHO ugly. Partial highlighting of lines
generally looks ugly, and this case is no exception.
(I could never understand the urge to modify the default colors. If
you dislike the defaults, customize the faces and be done with them.)
