While this might be true in general for Swedish...

... the hyphenation patterns we are using disagree:

  % The patterns were generated in such a way that they will hyphenate
  % correctly if \lefthyphenmin>=1 and \righthyphenmin>=2.

I thus ask you to revert your change (but correcting the error, of
course :-)

As discussed already, the right fix would be to make groff derive the
left and right hyphen minimum values directly from the hyphenation
pattern files.

If you have time, please update all pattern files from the data in the
`tex-hyphen' repository, for example,

  
https://github.com/hyphenation/tex-hyphen/blob/master/hyph-utf8/tex/generic/hyph-utf8/patterns/tex/hyph-sv.tex

(and applying the necessary massaging for groff).  All those files now
have YAML headers that help identify those values easily.

This has slipped my attention, sorry.
