Well, the issue is that new kinds of switches introduce new potential
for bugs. In the case of -Wl,-R..., I'm not even sure that you can
write that more than once per link, so absorbing one from xml2-config
might well break things on some platforms. Or, if you can write more
than one, we'd need to make sure they end up in a desirable order.
(cf commit dddfc4cb2 which fixed similar issues for -L switches;
it looks to me like the current coding would in fact fail to order
our $(rpath) correctly against one absorbed from xml2, and it would
not be trivial to fix that.)
I'm not, personally, eager to do that work for a requirement which
somehow hasn't surfaced on any other platform, nor on any previous
NetBSD release. I think NetBSD is way out in left field here.
