> I'd have thought that lots of countries have immunity for representatives / members of the executive which can only be revoked by a vote in the legislature. Isn't this quite common?

As far as I know it's rather common for official acts, not for criminal endeavours outside of the attributions of the executive branch.

From what I gather the Supreme Court decision ruled that former presidents have broad immunity, that's not common at all. I'd guess it's common in places like Russia or similar but not in functioning developed democracies.

I can only speak for Germany here, and the law here is, that, as a member of the parliament, you have immunity for anything relating to criminal law, as long as you hold your seat. As quite some members of the Government are also members of the parliament, they have immunity though that, but not through their government office.

The living practice is, that the legislative will void immunity upon request. I don't think they have ever failed to do so. The previous parliament voided immunity a staggering 25 times.
