As has been noted by Junio,

The "It" above refers to this change. Expecting comments from people to ensure
this change isn't a bad one.
FWIW, I am fairly neutral; I do not mind accepting this change if
other people are supportive, but I do not miss this patch if we end
up not applying it at all. The latter is easier for me as we do not
have to worry about breaking people's scripts and tools used in
their established workflows at all.
