TL;DR
Increase bulk inserter's maximum hand size to 16 for Space AgeWhat?
There should be an ability to make bulk inserters to handle 16 items per swing through research. "Transport belt capacity 2" already increases hand size for noral inserters 3 -> 4, it should include bulk inserter too, or make it in separate upgrate like "Inserter capacity bonus 8" available after unlocking stack inserters.Why?
- To balance stack and bulk inserters. Right now chest-to-chest (trains/assemblers) item transfer is more efficient with bulk inserters. It is unintuitive and doesn't fit stack inserter profile (to stack items on belt).
- It won't create backward compatibility issues, guaranteed through separate research, but updating "Transport belt capacity 2" probably won't either
- There are already a mechanic of upgrading hand size
- 16 is a power of 2
