I think the key decider in whether or not a RAIDed swap should be a must-have,

Why ? What has hot-swap to do with RAIDed swap ?

Also, it seemed like the discussion began in the context of setting up a home
machine, or something otherwise not as mission-critical. And in those cases,
almost nobody will have hot-swap.

As such, if you have to bring down the machine to replace a drive anyway, might
as well tolerate the risk of it going down with a bang (due to a part of swap
going away)

I disagree. Even without hot-swap, RAIDed swap allows you to control how 
and when the downtime happens in order to replace a faulty drive. 
Without RAIDed swap, you cannot.
