This bug has already been fixed in stable/9, apparently:

MFC r267812 (hrs): Fix ifname normalization. ifconfig_IF_alias{es,N} did not
work if ifname has any of [.-/+].
PR: conf/191961
Spotted by: jhay
MFC after: 3 days
------------------------------------------------------------------------
Personally, given that this a regression of prior behavior,
I'd love to see it go into a patch release of 9.3. Since its
not a security concern, I think this is unlikely to happen.
I have tested the patch in that revision (kindly send to me by
Hiroki Sato), and it resolves the issue I was seeing.
