But we were talking about my benchmark moving only by one character
(where the optimization loses) vs moving by 8 characters (where it
most probably wins since that's 8 interpretations and 8 bytes vs 1
interpretation and 1 byte).

The discussion was not about it being a default for everybody or not.

Yes, and I do agree with really asking for that one: we don't want to
put the burden of configuration on people who already have a hard time
using computers.
