I've checked with a test file and the output without @documentencoding
is close to what you ask for.
\input texinfo
@c @documentencoding UTF-8
@dfn{foo}
@code{code}
`bar'
`hello'
``oompa''
a---b
c--d

$ ./texi2any.pl test.texi -c OPEN_QUOTE_SYMBOL=\` -c CLOSE_QUOTE_SYMBOL=\'
test.texi: warning: document without nodes
$ cat test.info
This is test.info, produced by texi2any version 6.8dev+dev from
test.texi.
"foo"
`code'
'bar'
'hello'
"oompa"
a--b
c-d

Notice the OPEN_QUOTE_SYMBOL wasn't used in som of the cases.
With the @documentencoding line not commented out it is:
This is test.info, produced by texi2any version 6.8dev+dev from
test.texi.
“foo”
`code'
‘bar’
‘hello’
“oompa”
a—b
c–d

Tag Table:
End Tag Table
Local Variables:
coding: utf-8
End:
again with the OPEN_QUOTE_SYMBOL and CLOSE_QUOTE_SYMBOL not affecting the
the output for ` and ' - arguably a bug.

Yes I think it is a valid desire to have such an option, especially as such
an output is already available by changing the use of @documentencoding.
(That's why I made @documentencoding have this effect in the first place,
to give the chance to avoid having unnecessary UTF-8 sequences in Info files.)
Look at where the 'no_extra_unicode' flag is set in
Texinfo/Convert/Plaintext.pm - any option should use the same code as this.
