I should have been more clear -- Debian/Arch "just works" and (both low/mid/high users) do not need of anything beyond that. And both Alpine/OpenBSD do not provide an extra "need" to anything of what both Debian/Arch already does. Unless if Alpine and/or OpenBSD provides a feature that makes Arch/Debian obsolete in any way.... then yep, both will become more relevant.
Judging by various posts I’ve seen Arch and Debian both don’t “just work” for many users.
Also I really don’t get your point about providing a feature to make others “obsolete”… what do popular distros like Manjaro or Mint provide that make Arch/Ubuntu obsolete? And at least Manjaro has managed to be in the news quite a few times unfortunately.
The point of the article is that Alpine works, both on a technical level and as a project, without unnecessary drama.
