Reply to comment by Alan_Smithee_ in NASA wants new 'deorbit tug' to bring space station down in 2030 by DevilsRefugee

Basically, that is what the Request for Information (RFI) is asking. NASA is proposing the idea to use natural orbital decay or propulsion from the Russian Segment, then use the "space tug" to take over for the final de-orbit burn, plus any attitude and Delta-V adjustments during the final de-orbit events.

This announcement is NASA's mechanism to ask the aerospace industry what it thinks, and for the aerospace industry to give ideas.
