feature request: text=input option in .gitattributes

After requesting this as https://github.com/msysgit/msysgit/issues/164, I was told to take it upstream, so here I am.

I would like a text=input feature added that has the same behavior as text=auto, except that it defaults to core.autocrlf=input behavior instead of core.autocrlf=true. This would ensure that the repository is normalized and the text files in the working directory match what is in the repository by default. In mysysgit#164, I highlighted the behavior changes in a spreadsheet. This would still allow users to set core.autocrlf=true if they want CRLF on their Windows system. Using text=input instead of text=auto would ensure that Windows build servers like TFS and TeamCity compile libraries with code that matches exactly what is in the repository. This in turn, would make it much much easier to do source indexing using my SourceLink project. :)
