No it isn't, Pacman-key used to be broken and now isn't.  You will need to update archlinux-keyring.

Subject: [arch-multilib] Revoked keys

Hi,

I hope this is the right list to be posting this in. I was installing
the lib32 version of flash and happened to notice that the following
multilib packages are signed with a revoked key: lib32-nspr, lib32-nss,
lib32-curl.

Regards
