That’s essentially the same thing as a String-serialized big decimal, just less readable, no?

That’s quite a bit slower to process. At least if you’re converting to integers to do the calculations and the calculations would be quite a bit slower if you kept the big decimal type

True, but this is usually your least concern when you're dealing with monetary amounts/math.
