The original says this:

    blame: correctly handle files regardless of autocrlf
    
    If a file contained CRLF line endings in a repository with
    core.autocrlf=input, then blame always marked lines as "Not
    Committed Yet", even if they were unmodified.  Don't attempt to
    convert the line endings when creating the fake commit so that blame
    works correctly regardless of the autocrlf setting.

But if autocrlf=input, then the end-user expectation is to keep the
in-repository data with LF line endings.  If your tip-of-the-tree
commit incorrectly has CRLF line endings, and if you were going to
commit what is in the working tree on top, you would be correcting
that mistake by turning the in-repository data into a text file with
LF line endings, so "Not Committed Yet" _is_ the correct behaviour.

So I think that the reverting that change is the right thing to do.
It really was a change to break the behaviour to match a mistaken
expectation, I would have to say.
