Combustion Generator using ABM rather than Nodetimer?

[Beanzilla]

Is your feature request related to a problem? Please describe.
Why does the factory:combustion_generator use a ABM (Line 64) rather than a nodetimer?

Describe the solution you'd like
I feel the ABM works but so would using the nodetimer. (Just a dev looking at another persons code)

Describe alternatives you've considered
The only difference between the 2 is all factory:combustion_generators consume fuel and produce energy at the same time, where as the nodetimer would vary the energy as each fire at different times (since it would be almost impossible to place and activate them within a second).

Additional context
This is just a question, not an issue and/or really not even a feature request. (Just a dev looking at another persons code, that's all)

I used it because it was the default within the project and I didn't know much about nodetimers.
I think LemonLake used them because nodetimers weren't a thing back in the day.
Idk if ABMs ore nodetimers are more efficient, but I think producing energy at different times isn't much of a concern.
