Alright, well, I mean I’ve already signed over my copyright to FSF 
and this is a super small change.  Here’s the obvious patch, I 
hope it gets applied.

I don’t think it can negatively affect anybody’s quality of life. 
I don’t see any calls to find-dired and friends in the stock Emacs 
codebase, I don’t see any calls in major packages I might expect 
to use dired under the hood (e.g. neotree), and so I’d only worry 
about interactive use of the command.  But then without additional 
customization p-t-b-s-w should behave the same as s-t-b.

Then on the positive side this would allow customization if folks 
(like me) use find-dired and friends on a regular basis.
