PowerShell Core runs everywhere and installing it even on Linux servers now is an easy install away. Sure, no Linux distribution is likely to include it in the base install, but that doesn't necessarily make it niche. "Power user" tools are rarely in the base install and sysadmins have all sorts of install scripts or preferred images beyond just base distributions and few argue many of those "must install" applications were "niche" just because they needed to be installed when setting up a new server.
