The new .kokkuri:bake job is not working on trusted runners due to a few underlying issues:
- (fixed in v0.28) buildx does not handle # syntax lines or the BUILDKIT_SYNTAX build argument directly but always delegates to the dockerfile.v0 frontend for parsing and forwarding to the right gateway
- (solved with new buildkit-syntax-forwarder) The # syntax line parsing and forwarding is currently only in the dockerfile.v0 frontend
- The new buildkit-syntax-forwarder gateway is not yet allowed on all runners.
