> 'Built-Using' vs 'X-Cargo-Built-Using' dh-cargo behavior

So there is no plan to change this in dh-cargo? The tool the security team has that queries Built-Using can be modified to use the alternate field, if necessary, but we need to know if that's what we need to do. Are the tools that help with library transitions in Ubuntu going to cope with this?

Is there a plan to deal with this? Some sort of britney / autopkgtest check that could be added to flag these as needing to be addressed? Otherewise, this makes it more difficult to discern what might need to be rebuilt given an update to a given rust library.

I do appreciate the Cargo.lock packaging, that is helpful, though it means neediing to unpack binary debs to gain access to them, rather than merely accessing archive metadata for 'Built-Using' or 'X-Cargo-Built-Using'.

Thanks.
