Ok, I just feared that there might be other incompatibilities if
the texinfo.tex version and the texi2dvi version diverge too much.
I do not fully understand what you mean by
"this is the right way for the next development
version", however - if you think it is feasible to upgrade
to the most recent texinfo.tex version, with the
seealso->moreref changes and possibly further adjustments,
why not update now?
Do you suggest to do in it two steps insteads?

Seems pretty hacky to me to patch a present version of 'texi2dvi' for
using it. Maybe we can ship the whole 'texi2dvi' script, as we do it for
texinfo.tex? That way we could ensure that texinfo.tex and texi2dvi are
always compatible.
AFAICT (please correct me, if I make wrong assumptions here)
the script does not have other special dependencies, it only runs the
programs that
are given with TEX, PDFTEX, PDFLATEX etc.

To evaluate the first step of switching to texinfo.tex from
http://git.savannah.gnu.org/cgit/texinfo.git/commit/?id=77390b679e5f4833661fda9f34fd7da119bb942e
(The last version working without patched texi2dvi, at least for me),
I compared the PDFs generated with this version with reference PDFs,
compiled
against the currently bundled texinfo.tex.

See the results here:

Green color = reference version with texinfo.tex from out repo
Red color = version with texinfo.tex from aforementioned commit

It seems the differences are mainly in URL breaking and formatting, and
index formatting.
What do you think?
As a next step, now that David's MR is in, I would try to update to
current texinfo.tex
and compare the output again.
Then I could try to remove the @/ occurrences and as a last step
set @urefbreakstyle before.

Cheers,
