Ok, I found the answer (actually 2 / see other mail)

As for the "config" being part depends on which part of the man-page one 
reads.

But, anyway on the topic of "git switch"

Copying a branch (and maybe moving too) could be seen as an extension to 
creating a new one.
After all, after the copy operation there is a newly created branch. 
Only it has some more data with it.

So one could do
git switch  --settings-from <branch-with-reflog-and-conf> --create 
<new-branch>   <commit>
git switch  -s <branch-with-reflog-and-conf>   -c <new-branch>   <commit>

"settings-from" is just an example, there may be better names for it. 
Ideally not starting with a "c".

And using a name different from "copy" may be more accurate, because 
unless it is created on the same one <commit> to which the 
<branch-with-reflog-and-conf> points, then its at best partially copied.

On top of that options could be brought in, to copy only reflog or only 
config.

Using the above with an --force-create / -C would make it a "move branch".
In this case there could be a shortcut, if <branch-with-reflog-and-conf> 
and (the old) <new-branch>  are the same.
