Sending more data than you need is bad for two reasons. 1. It implies more precision, which in many cases is a flat out lie. Savvy users will know to truncate, round or something, but others will be lead astray. 2. It takes more space to represent. If the engineers storing double precious floating points had asked themselves if they needed to be sending these out at such a high resolution, they may have been able to cut the storage of these things down 50%. Though yes, there are probably bigger issues to worry about. Doesn't mean we should outright dismiss these points.
