Feature request: ProxyJump with Unix sockets

[Christophe Lohr]

Dear developers,
  The  ProxyJump  feature is nowadays implemented on the basis of a TCP port forwarding on the jumping host, isn't it?
As a result, this is affected by a AllowTcpForwarding=no configuration on the jumping host.

So, may I suggest a variant based on Unix sockets (such as -L or -R does).

Nice idea, isn't it?
Any volunteer to implement this?

Best regards
Christophe
