remote build: legacy builder cannot parse core22 snapcraft.yaml syntax
Metadata
Current evaluation
Marked won't fix: legacy-builder schema support was descoped in favor of the new remote builder, which accepts build-for; legacy support was removed by PR #5994 in Snapcraft 9.
Resolution: closed superseded
Reason: The maintainer closed the request as won't fix because the new remote builder already supported these keywords and the legacy implementation was descoped. PR #5994, commit b08f1a66e, subsequently removed the legacy remote builder in Snapcraft 9.
