No, none of it (if the patch is mechanically applied with e.g. git-am).

Sometimes, useful information does indeed get lost because an author
didn't consider it "above ---"-worthy.

That information is perfect for conservation mailing list archives.

The source repository metadata (commit logs) have other purposes:  Keep
book about what happened to the source code and why.

If the scope of a change is better captured that way, then OK.

The changelog is not only to learn what's new (i.e. a source of release
notes), it's also to learn what's old. :-)  I go through old changelogs
all the time because I deal with code with history older than my
involvement or too old for me to remember the circumstances.
