@charliebrownau @ryo @h4890 In practice, yes, but the jewishness isn't in the spec. If you just take the spec, make your own server + client, fully coompliant*, host your own instance and offer it to people, and hell, while you're at it, disable federation (or restrict it to only instances of your server - do that in nginx conf or whatever) you will encounter no jewishness.
Yet.

*Typo, but it can stay.
