Yes: in every call site, we just want to know whether two strings are equal
(ignoring case). APR doesn't appear to document what a "natural order
comparison" means, but looking at the implementation it appears to mean
something like leading spaces are ignored and a run of digits is compared as a
number rather than as characters. Without the semantics being documented I
would not want to use apr_strnat[case]cmp().

I think our one use of apr_strnatcasecmp is probably a mistake, or at least not
a particularly good idea.
