Unlicense is listed in https://spdx.org/licenses/

Debian does include software "licensed" like this, and seems to think
this is one way (not the only one) of declaring something to be
"public domain".  The first two examples I found:


This follows the format explained in
which does not explicitly include Unlicense, but does include CC0,
which AFAICT is meant to formally license something so that it is
equivalent to being in the public domain. R does include CC0 as a
shorthand (e.g., geoknife).

https://www.debian.org/legal/licenses/ says that


Licenses currently found in Debian main include:

- ...
- ...
- public domain (not a license, strictly speaking)


The equivalent for CRAN would probably be something like "License:
public-domain + file LICENSE".
