If it's strength - stepping up to 3/16" rivets doesn't cost a ton of weight and can be a lot stronger. If it's repairability / removability - rivet nuts combined with bolts are useful for mechanisms that have to attach and detach themselves a lot.

Bolts in gussets and tube can be a bit problematic - bolts going through both sides of the tube can crush it if you're not careful, bolts have more slop leaving a less rigid frame in some cases, etc. It's still quite doable though. You can even carefully size holes to accept both #10 clearance and 3/16 rivets, or #8 clearance and 5/32 rivets.

We haven't had many major issues with rivets- mostly just loosening over time in certain areas and needing replacement occasionally. I think didn't use the right rivets this last season though- we primarily used these when in the past we normally used something like this.
