YES!! It is a very much needed feature.
I have opened this feature request on the backend of the API a while ago: If a machine is decided returns the name/link of its decider · Issue #2 · bbchallenge/bbchallenge-api · GitHub
There is a technical inconvenience.
Decided machines are given in big index files: http://docs.bbchallenge.org/bb5_decided_indexes/
These files contain the big endian 4-byte representations of IDs in the DB of the machines that were decided by the decider, in increasing order of ID.
As it is not affordable to load those files in memory in my VPS setup, in order to implement your feature one has to implement a dichotomy of file seek that looks if the requested ID is in one of these files and returns the file name. Although it is standard algorithmic I have not have had the time to implement and test it.
If you had the time to wrap your head around it I would be happy to talk about this in more details.
The particular machine that you point at was decided by [Decider] Backward reasoning. Basically, any machine that is not a Cycler/Translated Cycler so far has been decided by Backward Reasoning (depth 300)
