Congrats on your new bike.
Wider bars give increased leverage for you to turn the wheel but decreased leverage when the wheel wants to turn the bars, say, if you hit a rock or root or something.
If you're not doing that kind of riding then trimming the bars shouldn't have too many downsides.
I understand the leverage situation. I'm not doing the sort of riding where leverage is important.
A gravel bike would have probably suited what I want to do just as well if not better but I wanted front suspension forks and they're generally not available on gravel bikes. As I mentioned I downsized the tyres to a size more commonly found on a gravel bike.
I haven't had any issues on the old bike with 600 mm bars with the sort of riding I'll be doing with the new bike.
In many ways I'd have been just as well off buying another set of rims for my road bike and fitting wider tyres (~ 38 mm) except the forks don't allow for tyres that wide and the gearing is a bit higher than required for the sort of riding I want to do with the new bike.
