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