More or less, yes.  IIRC it tries to limit itself to ELisp-related
manuals by avoiding all the manual except those that are in Emacs's own
`info` directory and those that are inside ELPA-installed packages.
Hence the list of exceptions being sicp and ada manuals since these can
be installed as ELPA packages.
