CRAN maintainers may have gotten someone to agree to take it over who
just hasn't finished fixing whatever deficiencies it has. However,
you might see how difficult it might be to do without "gdata" as well.

Is it permissible to copy the code from rename.vars (gdata) inside
my package with an hint:
" Function rename.vars Source code from gdata as gdata is unmaintained
since 2017-06-06 Rename variables in a dataframe
Author(s)
Don MacQueen (package gdata), macq\@llnl.gov."
it is the only function I am using from gdata.
That's definitely consistent with the GPL-2 license it carries as
long as you aren't trying to charge royalties for use of your package.
See:
https://CRAN.R-project.org/package=gdata
And the tarball is available at this link to make it easy for you to
do that.
Regarding my earlier comment about to gdata being potentially
obsoleted, I don't see evidence of that now: There is only one "Note"
in the "CRAN checks", and that would seem to be a problem more with that
platform than with the gdata package. The problem that Brian Ripley
mentioned in his email about this 2020-09-11 may have been with
something else that gdata used that has since been fixed.
I would normally prefer to let the gdata maintainers continue to
maintain a function like this. However, you seem to have a compelling
reason for copying that function and only citing the original for the
source of where you got the code. You might include, e.g.,
\code{\link[gdata]{rename.vars}}.
CAVEAT: Please ignore the above if contradicted by someone more
knowledgeable than I am about CRAN and R policies and recommendations.
