Are the two-duct portable air conditioners even available on the European market? They certainly don't appear to be a thing here in the UK as far as I can tell.

The omission is shocking, I can't seem to find any on UK or German Amazon.
Though on amazon.de I see at least one alternative to the Zweikanal-Klimaanlage or whatever you'd call it; a small split system with two condensers for just four-hundred euro. Though it seems like it'd likely warrant professional installation, and therefore €€€. https://amazon.de/dp/B06XTQKLXM/
Perhaps it is a Russian conspiracy to keep you all burning that sweet sweet gazprom oil (except the UK, congratulations!). ;- )
There's plenty of split units in the UK too, but those require professional installation and quite possibly also planning permission with a full professional noise assessment. No dual-hose portables though. I'm not sure why; we don't seem to have banned them like Australia accidentally managed to do (they imposed efficiency requirements on dual-hose units that portable aircon couldn't meet whilst exempting the single-hose variety).

Unintended consequences hall of fame. Have they reversed that, or is it just sorta sitting there, like a festering wound?
Try to get the two-duct ones, they are dramatically more efficient. This is reflected in the newer U.S. DoE capacity ratings, which take into account the various ways that single-duct portable air conditioners are not so great.

That seems really convenient, can anyone comment on the effect that has on efficiency? It seems like if the hot side is hot enough, re-evaporating the condensate on the hot side should improve efficiency.
