TBH, I'm more concerned about the other direction. Surely someone who
upgrades from an existing release to v14 and sets their compression
method to lz4 is going to want a way of actually converting their data
to using lz4. To say that nobody cares about that is to deem the
feature useless. Maybe that's what Tom thinks, but it's not what I
think.
