I think one thing could be desirable: to "kick" a connection to get it
to do a single retransmit. KA9Q-NOS (which I hacked on to make an Amiga
version (RhiNOS)) has such a feature. It is very useful if a connection
was broken for a longer time, and now it is available again, but TCP has
not caught on yet because it has backed off to a long retransmission

Or perhaps this condition could be discovered automatically somehow, but
that requires too much routing knowledge I fear.
