The commit to the daemon that bumped that protocol is dated Oct 15 2018:
--8<---------------cut here---------------start------------->8---
commit 6ef61cc4c30e94acbd7437f19c893f63a7112267
Author: Ludovic Courtès <ludo@gnu.org>
Date: Mon Oct 15 22:40:35 2018 +0200
daemon: Support multiplexed build output.
[...]
(%protocol-version): Bump to #x163.
* tests/store.scm ("multiplexed-build-output"): New test.
--8<---------------cut here---------------end--------------->8---
Which would have gotten distributed in a pullable 'guix' with:
--8<---------------cut here---------------start------------->8---
commit 532f92c8f39ef8fa9441bf0840ae642016fac7a5
Author: Ludovic Courtès <ludo@gnu.org>
Date: Mon Oct 15 23:54:20 2018 +0200
gnu: guix: Update to f9a8fce.
* gnu/packages/package-management.scm (guix): Update to f9a8fce.
--8<---------------cut here---------------end--------------->8---
That indeed doesn't correspond to the time when lzip was introduced.

That'd be nice indeed.
