I would like to have one stop request items for multiple individual train stops. This requires no temp steps being generated. I commented lines 281 and 283 from factorio-api.lua, but that generated errors each time a train arrives back at a depo. Commenting, line 165 from train-events.lua stops them, but Im sure multiple features are broken. Is there any chance that this could become a feature?

I think I got it, and I think it maintains all features.

factorio-api.lua function set_manifest_schedule

Remove/Comment the "create_direct_to_station-order" that are in the file. I think there were like 5. One of them might not have been needed to be removed I didnt think about it too much.

train-events.lua function on-train-changed
add a depot check to the bit that leads to the on_train_arrives_depot "if stop and stop.valid and stop.name == "train-stop" and map_data.depots[stop.unit_number] then"

Remove all bits referencing "Rail"

main.lua function se_add_direct_to_station_order

Remove the direct to station order so this basically does nothing.

I know this will never be used by anyone other than me, but yeah.
