Brew: MethodDeprecatedError: Calling GitHubPrivateRepositoryReleaseDownloadStrategy is disabled!

[pieterza]

My Formula stopped working, now install/upgrade presents:
MethodDeprecatedError: Calling GitHubPrivateRepositoryReleaseDownloadStrategy is disabled! Use a vendored GitHubPrivateRepositoryReleaseDownloadStrategy in your own formula or tap (using require_relative) instead.

Any recent changes made by homebrew?

Formula below:

class FooRun < Formula
include Language::Python::Virtualenv
desc "CLI for foo containers"
homepage "https://acme.org/"
url "https://github.com/foo/eng-sysdev-foo-cli/releases/download/v1.4/foo_run.tgz", :using => GitHubPrivateRepositoryReleaseDownloadStrategy
version "1.4"
sha256 "2ebe14d1830c5c52710c7168d4858a01c4f51e4bf8cd20a096795cfb04eff905"
head "https://github.com/foo/eng-sysdev-foo-cli.git"

bottle :unneeded
depends_on "python@3"

def install
venv = virtualenv_create(libexec)
system libexec/"bin/pip3", "install", "-v", "--ignore-installed", "-r", "requirements.txt"
env = {
:PATH => "#{libexec}/bin:$PATH",
}
(bin/"foo_run").write_env_script(libexec/"foo_run", env)
libexec.install "foo_run"
libexec.install "libs"
end

test do
system "echo", "TEST"
end

def caveats; <<~EOS
Jumo run has been installed.
Please run 'foo_run' which should now be in your path.
EOS
end

end

I require the private strategy and I pass a HOMEBREW_GITHUB_API_TOKEN

Please advise

I require the private strategy

This is no longer supported. You need to copy this into your formula yourself (as the message says).

Why this has been removed?

[MikeMcQuaid]

@victorcoder Because it wasn't used by any of Homebrew's supported formulae and we're a a volunteer run project who has to adjust our scope accordingly.
