That's what the standardization bodies decided. Let's stick with that!

The space could be optional, like the "use_iec" parameter.
I would certainly expect the space when appending a unit, e.g. "bit/s":
"700 bit/s" or "1.00 kbit/s".

Or when the appended unit is seconds, e.g. for latency/jitter:
"12.3 ms" or "123 us".

With raw numbers (i.e. without a unit appended), it's probably a matter of personal preference, so I'm not going to insist here.
I still prefer it, but only when a postfix is present.

In the SmartShare GUI, we output with the space, and accept input both with and without it.
