Some linux distributions are starting to use https://github.com/jinfeihan57/p7zip as a new upstream, as the previous one seems to be dead. I think it'd be a good idea to follow along.
By "some distributions" apparently I meant only Arch, so nevermind. Apparently the full package of 7-zip now supports linux as well, but apparently it's incompatible enough to warrant a new package sadly.
There is no need for fork of 7-zip since they release linux version. https://www.7-zip.org/download.html It would be best to remove obsolete p7zip and introduce official 7-zip.
Current version of p7zip in the portage is 16.02 It is likely subject of multiple CVE https://www.cvedetails.com/vulnerability-list/vendor_id-9220/product_id-30936/7-zip-P7zip.html
Proper upstream: https://github.com/p7zip-project/p7zip It's worth noting that most of the CVEs were fixed in gentoo's version of 16.02, and as such this bug isn't a security bug, but rather a request to unify cross-distro efforts into a single project.
