I only tried to make it terse for the bugreport, I hit this while I
was resolving conflicts during a merge. I aknowledge that using
"cherry-pick -n" to bring some contents to resolve a conflict is not
really nominal - my use case involves re-merging an updated "upstream"
branch, and bringing in fixups to the original merge.

I used "-n" precisely because I did not want to make a standalone
commit, and the message from the cherry-picked source has no value to
me. If it had, I would instead have used cherry-pick without -n, and
amended the commit afterwards.
In the general case, I only ever use -n when I'm squashing changes
and similar tasks. Are there use cases out there, where it makes
sense to keep that source message, when we don't want the commit to be
created right away ?

Well, seems to depend on use case - I find it a bug when the merge message,
notably containing the list of conflicting files, gets clobbered.
Also, I have not checked how git gui reacts, but I would assume that
when carefully and iteratively composing a commit message from there,
which is IIRC managed using .git/COMMIT_EDITMSG, it would not be
desired to get this content clobbered the same way.
To me it looks like the problem is that the commit message in
preparation is not considered precious information, when there are at
least some cases where it indeed should be. I'm not sure however how
that should be done:
* suddenly claiming it is precious (and require some form of -f to
clobber it) when it was mostly not is likely to break a number of
* looking at the context (are we resolving a merge or similar ?) to
consider it precious is likely to miss some cases
* declaring a new official location (or API/command ?) to store
considered-precious message being composed may bring its own lot of
