One concern I have, that might lead into rationale for the current discouragement,
is that I would hate to see a best practice that pushes a BOM into ASCII files.
One of the nice properties of UTF-8 is that a valid ASCII file (still very common) is
also a valid UTF-8 file. Changing best practice would encourage updating those
files to be no longer ASCII.
