So basically, suck it up and manually rearrange macros for every group?

And I'm not sure about your assertion that rearranging the visual party order has no effect on indexing. Pitbull has an option to arrange party frames by name, and when that's enabled party1 always targets the first character in the list, even if that character isn't the party leader. I'm not sure if this is a standard part of the Blizzard API though, so that may be the only situation that works as such.
Invite 1 other character to your group.
Set both using pitbull, or any unit frame mod you desire, to sort alphabetically so both screens unit frames look the same.

On character 1 type /target party1
On character 2 type /target party1

Notice that they target each other.

There are 5 units in a party, player & party1-4, there are up to 40 units in a raid, raid1-40. party designators still hold true in raids as well, of course only for your own party.

I'd be interested in seeing any ui mod that can reassign party1-4 to be whatever units it wants, but I don't believe it is possible, and I've got a fair amount of unit based code experience.
