I'm not saying don't do the other things too, but a ~5% saving (maybe more at a more typical gzip TX setting) for no semantic change at all saves some outgoing BBC resource but is more significant for the RX side in CPU, etc. Anyhow we can agree to disagree but many of my clients over the years have been very happy with 5% resource savings, although 5x is nicer when available...
