Actually, not necessarily a technical solution to a social problem,
for certain situations:
It solves the "linear real-time text problem".   TDD's (text
telephones) transmit as a single stream of continuous real time text,
with no message boundaries.

Gatewaying instant messaging (with XEP-0301 real time text) to text
telephones or other linear real-time text technologies, represents
some compromises when needing to backspace across message boundaries
(e.g. to the previous message).

The existence of XEP-0308 solves this problem.
And, the existence of multiple-message correction allows backspacing
back across more than one message (especially if several <Enter>
keypresses were accidentally hit on a TDD / text telephone)

Therefore, XEP-0308 (as agreed by me and Gunnar) is one solution to
the "linear real time text" problem; it makes it possible to backspace
across message boundaries, when gatewaying between linear real-time
text to instant messaging, and vice-versa.
