Hi all,
The implementation is pretty much already done in Mojarra, but we have 
not required BCP 47 support as it required JavaSE 7. Now that JSF 2.3 is 
requiring JavaSE 8 we could easily state it is a requirement.
Howerver we do have specification adjustments that need to be done in 
how <supported-locales> and <default-locale> in faces-config.xml need to 
be parsed (as that is in the specification).
As I said I don't feel strong either way.
So far we have one EG member saying +1.
Thanks!
Kind regards,
Manfred Riem
