The timeline is relatively strict: if we can get rough consensus before, say, Wednesday, I think we could respond "as the Reproducible Builds project".

It's really close to "until Wednesday" already, but in my opinion a 
missed opportunity in the original SBOM standard was:

 > The build tools/compiler are a material of your software executable

Knowing which exact compiler and compiler version was used is necessary 
for triaging certain security issues[1], and it's also critical 
information for any reproducible builds efforts.

At the moment this gap is filled by buildinfo files (each project having 
their own):

Also to any CISA staff following this thread: hi! 😺

[1]: Any security issue that isn't "the build input contained a defect" 
but "the way the build input[2] was processed was faulty".

[2]: This is assuming "the build tools" are not a build input, which I 
think is only half the truth.
