You are correct, we can't expect a new notation to be understood by most... it has to be learn and nobody is being teach a "point zeros notation".
BUT
The millennial generation are quick at switching to whatever is shorter and faster, and a bunch of zeros is a "problem" in our context. Often the new notation/abbreviations gets quickly adopted from the internet, no school involved. It is in that perspective that it might be OK to try something different.
Time will tell, and this "point zeros notation" might just die with this thread.
(Correction: I was referring only to the death of this proposal. The digitalindustry standard might shine from and beyond its own thread)
