• Not easily, honestly.

      WordPress on its own is very bare bones, you’re almost certainly going to want to install plugins, which by default can only be done from the builtin connection to WP servers.

      WP without plugins doesn’t even have basic things like gallery light boxes. Honestly it seems deliberate, since the easiest way to get a lot of basic features that should be in core is to install the automattic(the company that owns wordpress) jetpack extension, that also installs a bunch of data harvesting connections to their proprietary SaaS.

          • I don’t know, but I guess the reason why it isn’t done yet is because nobody perceives it as a problem. It would require a repository plugin to install plugins I think. But it all comes down to plugin distribution and deployment. Mostly if you want something outside the default repository you can just upload it to your own install / stack. If a developer provide alternative download ways. Like a github release for example.
