It is a maintenance item. I can’t recall how long ago I first did this but it’s 90% better. I could probably chase that 10% and reapply, but my time has been reallocated the last two years with my boat refurb/upgrade project.
That’s interesting. These aren’t like head studs or something torqued super hard that stretches. I may replace my hardware next time but I haven’t had any failures yet.

Be ready with a set of files to remove any burrs and galling caused by lack of lube from the factory.
You have to remove burrs that were cause by galling due to the lack of grease from the factory. After you make the repair and apply appropriate lubrication, I would recommend that the drive shaft is at some point inspected and that more grease is applied depending on your situation/use. Hence, it becomes a maintenance item if someone cares to do so and for no other reason.
I think I asked earlier in this thread, but you seem to be the best one to ask now. GM has a grease zerk for their front sliding spline driveshaft; could one be installed at this location?
Unfortunately I don’t think the design of the splines and the driveshaft tube on our trucks are the right fit for a zerk fitting. I’m going off memory here so anyone can feel free to correct me, but the wall thickness is relatively thin(it’s not a solid shaft end piece that is milled with splines) and the surface area is rather large. I don’t think a single well-placed grease fitting would disperse grease uniformly or effectively.
