possible to see intermediate hashes on build?

[gcb]

i'm still on legacy builder and i do get the intermediate hashes, and honestly it is the only way to debug image build issues conveniently.

I can enable it on composer too, with the (undocumented?) option docker-compose build --progress plain

Is something similar available on buildkit?

[gcb]

the workflow i want is to jump on a failed build and test that one failed command right away, not start from scratch from the FROM line and run all steps manually till the failure can be investigated.
