That wish is fine until you start working with others. Then you get 50000 line diffs that are somebody changing a single line on *their* system, because they happen to use the opposite system to the last person to check code in.  I think the best middle ground here is to say `-text` or `eol=input` for files that *must* be encoded a certain way.

As for linters: linters require people to run it, and we still have to encode those rules somewhere - just not gitattributes. As far as I can see this is the lowest overhead and most reliable *pragmatic* option that has the nice property of being fully integrated into the tooling, transparent to end users, and in a known (semi) central location.
