Community packages of John the Ripper, the auditing tool and advanced offline password cracker (Docker images, Windows PortableApp, Mac OS, Flatpak, and Ubuntu SNAP packages)
Currently, OpenCL flatpak works (could work [1]) for the CPU [2].
At the moment, the only way to use a john "containerized package" with GPU access is via Docker. Offering access to all important john resources securely via flapak [3] is something that offers value to the end user.
[1] OpenCL is disabled in flatpak binaries.
[2] I've tested it a bit, but unfortunately I don't own any suitable hardware. I've never tested it with a GPU.
[3] I mean, OpenCL in a sandboxed app.

Deploy john with OpenCL support in a secure, sandboxed and containerized way will allow users to use the full power of the tool, protected against a good number of flaws that may exist in the binary during the development process.
I won't be able to test it (no hardware). But the changes are safe and easy to “understand”: enable OpenCL and add the necessary permissions/extensions.
I use snap, but IMO flatpak is taking a better route.
