Some others mods include more machines powered by steam, like the press from Arig, or the pressure forge from Crucible. Would you make some special compat with them in the future so that they can craft wood pulp without steam?

Speaking of which, I'm actually kind of curious about why you did not allow wood pulp to be crafted by vanilla machines like biochambers at the first place, in addition to assemblers.

Wood pulp can be crafted in assembling machine 2 and 3. I have no plans to add more machines to that list. Steam should be required in all cases.
