I am yet to find one without it, unless you include Windows, consoles, or table/phone OSes, embedded RTOS, which aren't anyway proper UNIX derivatives.

According to the internet (can't check now) Alpine doesn't come with perl installed.

So a distribution mostly used to deploy containers.

I don't agree with "any modern system" but some modern systems certainly don't come with perl.
