I'm a bit worried that having one id for everything will be more
difficult to maintain, that's why I created WMI_OP_VERSION in the first
place. IMHO it's lot cleaner codewise to have one id for WMI interface
and one id for HTT (eg. HTT_OP_VERSION). What do you think?

Maybe not the rename, but yeah, something should be decided before the
bump up.
