Yes. That looks to be the case. All of the *utime* methods are related.
utime() and utimes() are wrappers and the two underlying POSIX methods
do a permissions check which has stat. If you always get an error from
stat_h,
then you won't try the utimens_h handler.

I also noticed a couple of the files included <sys/stat.h> but didn't need
it.
I'll delete that also.
