Hi Dhruv,

The counterpoint is that if tradition was enough to forbid us from adopting 
small improvements, there’d be a lot less progress. But it’s not a big deal, we 
can leave it to the discretion of the WG and authors. Regardless, a new version 
is needed to address Lars’s DISCUSS — I think all the necessary conversation 
has taken place, we just need version 08 with the agreed changes.

Thanks,

—John
