Just curious if anyone pumps or vacuums oil for changes? Thought it might be slick, no removing 3 bolts, not that it is hard, but then no oil container to drain. Problem though would be maybe not getting all the oil, and still have filter. Anyone?

I'd think there's great(er) risk of sediments, sludge and metal residue remaining in the engine unless you drain it via the drain plug/s. I don't know if the R3 has it but some bikes have magnetic drain plugs to catch worn of metal flakes from the internals.
Bottom line is - i wouldn't vacuum out the oil, even if i get your thinking/point.

When doing oil samples it is recommended oil be hot and caught amid stream.
So from the context it is saying there are particles left behind in a sedentary situation.

Isn't it true the oil goes through the filter first, so harmful particles to the engine are caught? Ones that go through filter are not harmful and even a little at bottom after vacuum would not cause trouble?
You know how we do things the same way sometimes cause of history.
Remember that NYC study where they had one group of taxis, stop and go driving, with oil change at 7500 miles, vs another group at 3k miles. After 100k miles tore engines down, no difference in bearings wear etc. I do mine at 5k knowing not needed. Kinda dumb really.
So it may be same with vacuum?
I could be the guinny pig. But like most wouldn't chance it since pretty simple the old way.

I use to change my mercedes 300d by vacuum pump, but the rockets oil system is a entricate oil system from what people say (From post ive read) who understand this complex design, meaning i dont think youd get it all

Tried that using my boat vacuum pump system, but couldnt get all the old oil out. The new Rocket uses a dry sump and retains much of its oil in an internal tank
and doesnt drain down fully to the pan like a wet sump bike does. I threw out the hex drain plugs and replaced them with magnetic drain plugs with a regular bolt head.
The size is 14x1.5
Much easier to remove the plugs now with a wrench instead of the hex wrench. Dont know if they will catch much on the magnets, but will post a pic. at my next oil change
of all three magnetic plugs to show how much if any is caught. All wet sump engines use multiple drain plugs to get all the oil out of the galleries..
My Z-51 C-7 Corvette has two drain plugs that use the same size plugs as the Rocket. DId magnets on those two also. Engines that share the clutch, drivetrain gears, and engine
with the same oil are much tougher on oil because of shearing than a regular car engine, or a Harley.

Harley's have only one drain for the oil. So you can not drain all the oil out. Kind of sucks. You end up with a quart of old oil and no way to remove. I will take the Rockets three drain plugs any-day of the week.
