Nope. It's a placeholder. Nothing more. It's an easy way to tell if the default setting has been changed. It's apropos of nothing.

Here's me editing one of the xhtml files in an epub using Notepad++ that I initiated via Sigil's Open With feature.

And?

Anyone who tells you that environment variables are another crappy Windows thing is an idiot.

That's because environment variables exist/work in MacOS. Contrary to what anyone has disdainfully told you about them. I can't imagine why any knowledgeable Mac user would tell you Macs "don't have them."

But no. <SIGIL_DEFAULT_TEMP_HOME> is not an environment variable because it's not an environment variable. I don't know how else to explain it. It's an unspecified default value, or it's a file path manually selected by the user.
