As far as I know, the default color for the current line was setup that way for accessibility and usability reasons, much like the alternating background color in lists. I guess that you would probably need to have usability or accessibility studies or proof to support your suggestion.
Also, would like to suggest text editors not saving backup files by default - just clutters things with two of every filename.
My personal opinion is that these backups have saved my ass a couple of times. And it's much easier to delete them or disable them than it is to recover previous versions or to actually discover that the feature exists. But that's just my opinion, probably shared by others since it has been the default for quite some time now, and I've not seen anyone complain about it... until now of course.
Don't know if it's probably more useful to file a bug report on this as a wishlist in
