Nah, I decided on em dashes with no space many years ago. In Australia, en dash with spaces is more popular now. Em dash without spaces is the older style. I deliberately chose the older style: for I say, the old is good.

Just wait until I decide to go all in on TWO-EM DASH⸺I have thought for a long time that EM DASH isn’t wide enough. Or maybe THREE-EM DASH⸻though it’s normally too wide. But alas, font support isn’t good on these so you might get bad alignment or line-height inconsistency; and I might end up wanting to surround it with THIN SPACE or HAIR SPACE, and HN mangles exotic spaces to just SPACE. :-(

(Honestly, my original comment would be improved by using TWO-EM DASH, or maybe even THREE-EM.)
