Well, the nice thing about at least agreeing on using e as the notation means its easy to understand variants which prefer subsets of exponents. 500e8, 50e9, and 5e10 all are reasonably mutually intelligible. I think sticking to a subset of exponents does feel intuitive for talking about numbers frequently encountered in everyday life, but seems a little contrived when talking about large numbers. 4e977 seems to me like it isn’t much easier to understand when written as 40e976 or 400e975.
