Maybe you judged only after a quick glance? I would not call it
useless. See https://wiki.debian.org/ReproducibleBuilds/About on
motivation for it for example. As a user concerned about integrity of
the software I'm running, this approach is desirable. 

As a developer eventually shipping firmware built by a ptxdist based
BSP, I'm also interested in reproducible build artefacts.

You might not need it for your usecases, other people would disagree,
thus calling it garbage … well … I would not do that.

Junk, garbage, see above.

With kind greetings
