I’m in agreement with this page being in need of improvement. I’m not all
that comfortable with this particular proposal. It adds some of its own
concerns and doesn’t remove some existing ones.

As an aside - recent comments about the undesirability were made - and
while I’m accepting of their usage generally this one seems like a good
candidate for removal if we do update this page.

My biggest qualm is the wording that makes it sound like a window frame is
an option in lieu of looking at the partition when there is always some
default frame in place.
