This sounds reasonalble to me: a link was requested, it might not matter
which kind, and only one kind of link can be created. Thus 'ln' could
try to do the right thing and create a (symbolic) link.

Printing a helpful warning message that a symbolic link has been created
instead of a hard link, because a hard link cannot be created (perhaps
less verbose) would help at least a little bit. A new option that is
needed to enable that behavior would prevent the confused users, until
distributions start to add it to the default aliases.

I immediatly searched for the respective option and changed my aliases
to not quote 'ls' output. ;-)

I did not like that the default output of 'ls' was changed, but at least
I can disable this anti-feature.

This sounds reasonable to me, but others have different view, see your
'ls' example. ;-)

Anyway, IMHO Linda's arguments for the specific change requested
have merit. I personally would prefer an option to enable that new
functionality instead of making it the default, if someone were to
implement said functionality.

Design your product to please the users.
