There's a lot of talking about `xz` compression time in this thread,
but the main take away from the Fedora change proposal is that they are taking this direction to save _decompression_ time.
That's the metric that actually matters.
Now I get it that some users consider decompression time a non-issue,
because what matters much more is the nb of bits transmitted through their long-distance modem,
and sure, their use case is the only that should matter for everybody, right ?
The world has changed so much in the past decade.
Serving an isolated desktop on a remote island is no longer a "thing" in the Linux world, if it ever was.
What truly matters is to serve fleets of workstation in large data centers, flooded by high-speed local connections, serving multiple VM and container per system.
Think AWS, or equivalent, that's where investments are.
And in this setup, the decompression speed improvements are just _huge_,
it directly translates into much faster boot time and VM preparation.
That means less resource "in transit", mobilized but not yet able to serve their target scenario.
This directly translated into actual infrastructure savings, hence money.
Not even counting the better experience due to lower latency, with pervasive benefits.
It's just a no brainer.
