ajamez,
I really agree with most of your post,
with only one exception:
even though I'm not 100% sold on the name "bits".
I
very much oppose to use the word "bits", because, as you can see from our short conversation above, it is not clear what "bits" actually means.
There are multiple proposals for using "bits" to mean different things, and this is a clear No-Go for using it as a unit.
Units may not be ambiguous.
"Bits"
is ambiguous.
Instead, I recommend using the word "zib":
1 zib = 100 satoshis = 1 µBTCThis was always communicated clearly, there was never a different meaning for the word "zib".
That's what makes "zib" suitable as a unit.
