Indeed, I would have written this, as the trailing double colon is
needed in the prepend context of using the variable.

arm-ffa-transport.inc:FILESEXTRAPATHS:prepend := "${ARMFILESPATHS}:"
linux-yocto%.bbappend:ARMFILESPATHS := "${THISDIR}/files"

But as you said, it works, so that's typically enough barrier to keep as-is.
