Five simultaneous axis is unlikely for hobby anytime soon since it is export controlled ;)
Beyond that its seriously annoying to home and align a five axis machine. These machines would at least need absolute encoders to really be usable for hobbyists. Some do now but it's still pretty rare.
(but yes, most software for that is ITAR-regulated)
but for 3D printing the forces are a lot less and there's a lot of potential, and there are other cutting options such as wire EDM (saw a hobby-level implementation for that recently)

Actually, you can order a cheap Genmitsu CNC, the RATTMMOTOR 5-axis upgrade, and the BIGTREETECH SKR 3 EZ controller board from China. GrblHAL is a suitable open-source firmware. And Fusion 360 will happily create the toolpaths.
So I don't understand which part is export controlled.
Well-made CNC machines are a controlled export item in the U.S. if they have the ability to precisely machine certain materials to create certain parts. See recent news stories about Haas CNCs churning out Russian weapons.
Multiple axis CAM software is also export controlled.
The folks who make the hobbyist machine I linked have a page on this:
I find that quite fascinating. So it's illegal to export a high-quality CNC machine from the US. But, apparently, it's legal for China to sell a clone of that machine to those exact same people who wouldn't be allowed to buy an original from the US.
