I think the reason that people disagree about the details is because
they have different use cases for this feature in mind.

To reconcile these two opinions, we could introduce a user option
which would invert the default: make strongly-dedicated the default
and weekly-dedicated the optional kind requiring C-u.

Alternatively, we could use switch-to-buffer-in-dedicated-window as
that user option: if the user sets it non-nil, we could take that as
an indication that they prefer the strongly-dedicated default.

WDYT?
