# awscli/{botocore,s3transfer} are vendored *forks* in v2, not copies of the
# upstream releases: the v2-only features (SSO, the auto-prompt, the new
# `aws s3` CRT transfer manager) live in those forks.  Unlike the v1 ebuild
# they must NOT be unbundled, and dev-python/{botocore,s3transfer} must not be
# pulled in -- they would only shadow the forks.
