That's not too different from macOS's approach, instead of compose-character you learn the shortcuts for composing with the diacritics or special characters. After I learnt them it has always been quite efficient, I can write in Swedish or Portuguese without thinking.

Just curious why compose-character combo for å is a/o though, it would make more sense to me to be a/a.

> Apropos of Swedish keyboards, though, when a Mac is inflicted on me, the horrible contortions necessary to get all the usual programming bracket symbols ({[]}) are infuriating.

Absolutely agree, I never use the Swedish software layout even on keyboards which are physically using a Swedish layout, it's maddening finding the {[]}-_+=@ chars...
