Approved.

That is IMHO a mistake, and we should gradually correct it.  The
Texinfo cross-references (and thus index entries) refer to the
enclosing node in the Info version, so having smaller nodes makes sure
you will land close to the stuff you are looking for.  (There's the
new @anchor directive which is free from this limitation, but older
Info readers don't support it, so we should not yet use it too much;
and index entries don't produce @anchor's anyway.)
