Cabin floor bolt/screw removal, consequences?

[Robw_z]

I want to remove these screws to do some rust treatment. I assume the unibody is welded, so I’m confused as to their purpose? Anything I should be cautious about in removing them? Thanks for any insights,

I went ahead and removed them, after I realized they are essentially just plugs for models that didn’t come with a center seat. They are plastic not structural.

Those are just plugs to fill the bolt holes for the seat rails that would be bolted there if you had a middle seat. After paint replace them along with some sealant, maybe a butyl based something...
