It is false: if I choose to delete swap file (in the vim prompt, not from
shell)
it will use .foo.swp, not .foo.swo.

I have swap files to prevent myself from editing one file in two vim instances
simultaneously. Though sometimes something goes wrong and vim or the whole
system crashes, but I never needed them to recover anything. All you need to
have the same behavior is to train yourself to do «paused for thinking - hit
{lhs of your mapping to :up} to save file». For me it happens even more times
then «stopped inserting - exit insert mode».
