I have in the past suggested an additional connector inside the phone.
This would bring out:
USB D+ (simply connected to the external connector)
A connector similar to Digikey HFL110CT-ND - a 10 way vertical mount
cable connector next to the battery connector. This is around $.30 at
1000, and slightly cheaper ones are availabe.
In use, this is coupled to a replacement or modified middle-case of
which with a bit of FPC goes to a connector mounted on the middle-case
that engages with a modified back when plugged in.
A much cheaper alternative would be to bring any of these signals not
present out to an enlarged debug connector.
This would mean that a $10 or so adaptor cable would be needed for
anyone with an old debug board, but...
A small flex cable would then again be used to bring the ~10 wires -
eliminating unneeded ones - back out to another user-accessible connector.
