When you compile the v4l-dvb or v4l-dvb-experimental tree it will
update your whole v4l and dvb subsystem.
As soon as you do so it won't work to install any other external media
drivers anymore, beside that v4l-dvb is much bigger than the snipped
out em28xx driver.
em28xx-userspace2 and userspace-drivers only contains the drivers for
em28xx based devices and won't affect any other drivers on the system.
Since the uvc driver is also out of tree it won't break
compiling/using the uvc driver against the current running kernel.

The kernel sources are needed because some internal headers are needed
for the em28xx to build an alternative tuning system for hybrid
radio/analogue TV/DTV devices. It should work flawlessly with older
kernel releases where v4l-dvb already fails to compile.

It's also easier to keep backward compatibility while not breaking any
other drivers on the system that way (and this is seriously needed)

Beside all that:
There's a .deb package available I posted the link very early already
compiling from source can always introduce some mess so you better
know what you do otherwise you have to learn how it works...
The build scripts already do alot work there for several different distributions
