Note that in your suggestion above, you cannot insert a new key in between existing keys - only at the end; so
although "cleaner", it has less functionality (depends also on the sorting, which is another issue; if there is auto-sorting, it doesn't matter).
It is also a matter of taste, I guess, so no absolute right or wrong here IMO.

Or no sorting at all (i.e. simply display in order of filling)...
In any case, open issue has been added to the wiki.
