Docker Engine v20.10 and up includes optimizations to verify if images in the
local image cache need updating before pulling, preventing the Docker Engine
from making unnecessary API requests. These optimizations require the container
image registry to conform to the Open Container Initiative Distribution Specification
(https://github.com/opencontainers/distribution-spec).
While most registries conform to the specification, we encountered some registries
to be non-compliant, resulting in `docker pull` to fail.
As a temporary solution, Docker Engine v20.10 includes a fallback mechanism to
allow `docker pull` to be functional when using a non-compliant registry. A
warning message is printed in this situation:
WARNING Failed to pull manifest by the resolved digest. This registry does not
appear to conform to the distribution registry specification; falling back to
pull by tag. This fallback is DEPRECATED, and will be removed in a future
release.
The fallback is added to allow users to either migrate their images to a compliant
registry, or for these registries to become compliant.
Note that this fallback only addresses failures on `docker pull`. Other commands,
such as `docker stack deploy`, or pulling images with `containerd` will continue
to fail.
Given that other functionality is still broken with these registries, we consider
this fallback a _temporary_ solution, and will remove the fallback in an upcoming
major release.

This hack was added in an attempt to continue supporting the experimental
(non-buildkit) `--platform` option, by dynamically updating the API version
required if buildkit isn't enabled.
This hack didn't work, however, because at the moment the override is
added, the command is not yet attached to the "root" (`docker`) command,
and because of that, the command itself is the `root` command;
`cmd.Root()` returned the `build` command.
As a result, validation steps defined as `PersistentPreRunE` on the root
command were not executed, causing invalid flags/options to not producing
an error.
Attempts to use an alternative approach (for example, cobra supports both
a `PersistentPreRun` and `PersistentPreRunE`) did not work either, because
`PersistentPreRunE` takes precedence over `PersistentPreRun`, and only one
will be executed.
Now that `--platform` should be supported for other cases than just for
experimental (LCOW), let's remove the 'experimental' check, and just assume
it's supported for API v1.32 and up.

To create this, I ran every JSON document through `jq -S` (which sorts the keys and consistently pretty-prints the result in a format which matches the majority of documents in this file).
