Yes, the USSF has as part of it's "SpaceWerx" program a funding initiative called Orbital Prime, which autonomous on-orbit servicing and de-orbiting is a major focus. The summary headline is any private technologies that enable autonomous "RPO" Rendezvous Positioning Operations, will in turn enable activities such as autonomous repair and refueling (one of the main reasons orbital space vehicles reach end of mission is they run out of fuel), and in cases where refueling and repair aren't possible, autonomous "tugs" can dock and execute a deorbit burn for the decommissioned space craft. I was on one of the awarded teams for Orbital Prime last year, its very exciting technology and equally exciting to see serious amounts of funding materializing to tackle this problem.
