I concur — having added it as a third level symbol (AltGr + dash for em-dash, AltGr + Shift + dash for en-dash) to a default layout for Linux in early 2000s, it has become my signature of sorts.

If I am to be called out as an LLM, at least I can lay a claim I've been one for 20 years!

I do eschew one tradition surrounding it — the one of using no spaces around it — despite recommendations of different Manuals of Style and typographic norms. It simply looks better with more breathing room.
