Sorry for my previous wrong answer.
It looks like Heiko never uploaded that version and when I reconstituted a build system for these packages I only had the ctan release to start from. We could try mailing him and see if he still has a copy of that version.
A StackExchange answer talks about a
iflang
version2014/04/29 v1.7
with a\IfLanguageFamilyEnglish
macro. However, this does not match withiflang
at CTAN, that has version2018/01/21 v1.7
and does not contain this command.
