Just found https://mods.factorio.com/mod/RailLogisticsDispatcher
This seems to do almost the same, although slightly different.
They do have some good ideas:
1) I like the status lamps
2) The config UI is great
3) Neat status UI
4) Train type configuration, similar to allow-lists but way more powerful

That said, your mod got a bunch of awesome features as well. :)

You seem to have the same goal, maybe both of you would be interested in merging into a single mod?

hah yeah I don't know the mod developer but by coincidence we created and released both mods at around the exact same time.
I would be open to sharing code with them and adopting some of their code. However due to Factorio api limitations I don't really think it would be possible to fully merge the two mods.
