Having debugged issues with bad DTBs in the past without having this
information, I don't see it as being majorly helpful -- the DTB is
relatively simple and can be decompiled.

You don't gain much from being able to read which file it was built from
on a random server you don't have access to, and if you do have access
to the source it's relatively easy to discover the file it was built

So unless there's a really compelling case for this, I don't see the
point in having it.
