Despite spaceship floor being a valid tile for reinforcing, space variants of machines being placed on ship floor on a planet are not being reinforced.
From what I can tell, this is specifically the "grounded" variants SE makes, that won't be able to do specific space recipes. Other entities, like ship walls, reinforce fine when placed on ship flooring. This also used to work in earlier versions of Stable Foundations.
I believe this is due to reinforcement.lua checking who placed the entity when reinforcing, while SE takes the normal placement call and replaces it with a script placing the grounded variant - Unlike most buildings, there is no "last user: Renniuq" when placing a grounded space building, so it probably doesn't count as me placing it when that reinforcement check goes off.
