Hm.

I'm a bit confused, as the spec in other cases tries to be as strict as
possible for serialization.

Is there a reason why we don't just disallow leading 0s, or trailing 0s
after the decimal point? In particular in the case of Decimals, some
implementations preserving "precision" and others not doing so could be
problematic.

Best regards, Julian
