Well it is possible for someone to have cloaking ability on their ship and still be cunning, but I agree with the points that it's not necessary.
The only reason why I would've been okay with cloaking devices in SW is because it was mentioned by Needa. It's just a matter of interpretation if it means literal stealth or just "off the scanners", which for me I could've gone either way.
But when in doubt, keeping things looking and feeling as close to the original as possible is the best way. Therefore, not having stealth on Slave I and only increasing the following distance, as Ady already did, would be best after all.
