> For example, the decimal expansion of 3^3^3^3 <https://oeis.org/A241292 >
is given a huge offset equal to the number of decimal digits in the
integer. Doesn't it make more sense to see the expansion as a finite *list*
of digits with offset 1?

OK, as long as you are just talking about large /integers/, that
seems like a reasonable suggestion.
