Can new @nodedescription command be used for @detailmenu?

[Gavin Smith]

I've changed texinfo.texi not to use explicit @menu blocks in most cases,
using the new @nodedescription command for the information that was
previously in the @menu blocks.

However, in the Top node of this manual, and many Texinfo
manuals, there is a @detailmenu block.  I believe this can be
updated/regenerated in Emacs automatically.  However, I feel it would
be better to have a way for texi2any do it.

Have I understood this situation correctly?
