I would leave it in and include a large warning that this installation
is experimental/unsupported due to varying reliability issues.
I would also include links or suggestions on how to find the history on
RPI implementations and issues.
I think the RPI is a powerful solution and it will only get better.
Having more access to the installation (even if it has issues) will
encourage experimentation
and make it easy for someone to establish a baseline system so they can
fix the underlying issues.
I've been using the RPI 4 as a VPN endpoint for remote access and it has
been very reliable.
There are so many RPIs out there now, that if a specific version is
required to make it work, it should not be difficult to find that version.

Some patches were submitted, and applied, and seem to work for the
submitter, but not for anyone else.
I have spent over a week trying to build a working kernel package, and
whilst some of them have worked for me, with the hardware that I own,
there has been no reported success for anyone else.
I propose that we remove the kernel and linuxcnc packages and edit the
docs to suggest that it can be made to work, but is not supported.
