Whatever floats you boat.
Personally, I like having the side stand as it is sometimes very handy if I just want to park the bike for a minute or so.
I disconnected my safety switch about 2 years ago and I haven't had a problem with riding off with the stand down but then, I tend to check for things like that and the feel of the front brake lever before I even start the engine.
Getting back to your question, if you did just unplug the electrical connector where the side stand switch plugs into the main harness you would be sure it wouldn't cause any problems with the engine.
Just because the switch is disconnected you could just vow to yourself, "I shall NEVER use that side stand again. It is a figment of my imagination so although it appears to exist it doesn't! Henceforth I shall only use the center stand."
If you do this and keep your word, your problem is solved.
