It argues the topic pretty well: xz is unsuitable for long-term archival. The arguments are in-depth and well worded. Do you have any argument to the contrary beyond "sour grapes"?

It's not relevant to the current issue at hand.

If you say "sour grapes", then back down your bold statement or don't say at all.

> xz is unsuitable for long-term archival

Neither is lzip since it doesn't contain error correction codes. You can add those with an additional file (to any archive) e.g. via par2 but then most of the points in the linked rant become irrelevant.
