Wind drag strips it off. In space, you could just glue it on. If you
can build gyros and sensors sturdy enough to withstand the launch, you
could use the space in the sabot for guidance.

You could use gyros, but spinning the projectile is very simple. Depends on size and type of shell.

And yes, stabilization does matter, even in space. It's not just cross-winds and wind resistance, it's also that any projectile will tumble faster or slower as a result of slight asymmetries while coming out of the barrel.
