I have done further reading into the fact that in order to help human maintenance, the soft inflatable materials could withstand temporary pressure increases. This would allow humans to go in without suits for a small amount of time, which would not be that bad for either the humans or the structure. But further research is needed and in the meantime very light spacesuits could be used for that maintenance, which can be complementary assisted by remote controlled robots attached to the ceiling or some VR techniques like the robots performing medical procedures. The science is there and it's so vast that everything can have a solution.
