Same for arch. Don’t use it for a server. It deleted php 7 and upgraded to 8 which broke my WordPress website.
For example, I use several Raspberry Pi as servers and have Arch installed on all of them. And it simply works. I therefore do not consider such sweeping statements that Arch cannot be used for servers to be correct.
It depends on the individual use case.
For example, was Wordpress already compatible with PHP 8 at the time? Because I also use a webspace at uberspace.de. CentOS is used there and not Arch. Some time ago, I wanted to install Hedgedoc there, but it didn’t work because node.js 20 was standard in my case, but Hedgedoc only supported version 18 or even 16 at the time. So it would only have helped to define a lower version as the default. This would have meant that another tool that required a higher version would no longer have worked.
