Revert "Merge pull request #141192 from helsinki-systems/feat/improved-socket-handling2"
This reverts commit 57961d2b83, reversing
changes made to b04f913afc.
(I.e. this reverts PR #141192.)

While well-intended, this change does unfortunately introduce very
serious regressions that are especially disruptive/noticeable on desktop
systems (e.g. users of Sway will loose their graphical session when
running "nixos-rebuild switch").

Therefore, this change has to be reverted ASAP instead of trying to fix
it in "production".
Note: An updated version should be extensively discussed, reviewed, and
tested before re-landing this change as an earlier version also had to
be reverted for the exact same issues [0].

Fix: #146727
