Some of the arfs I've owned had very inadequate gear support structure. The deficiencies include too soft of wood structure where the T-nuts pulled through the wood, poor glue bonding, inadequate glue surfaces and splitting of hardwood mounting blocks.

Having entered the hobby nearly forty years ago when there were no ARFs, there were few gear failures and few planes that were seriously damaged due to the gear structure being too strong. Sometimes the gear themselves suffered... but rarely did the plane suffer because of gear mounting that wasn't designed to fail. Thus... I don't think I buy into the idea of keeping the gear support where it will rip, but I speak in general terms. No doubt there are cases of serious damage done by gear that didn't collapse easily.

If I were to disposed towards forgivness mounting.... I'd use Edwin's suggestion to use nylon bolts.

I beef up the gear and firewall on every ARF. My preferred method for additional gear support is

1. remove the existing T-nuts
2. using 3/16" light ply bought in small packs at the craft stores and ripped 1" wide and given small drill holes up 1/8" along what will be the bottom inside edge
3. these strips are mounted vertically around the perimeter of the gear mounting box to add glue surface to the inside of fuselage
4. fit a 1/4 aircraft grade ply above the existing gear mount (this is given small drill holes into the edges all around)
5. drill from the bottom through the holes and replace T-nuts
6. use longer screws if needed and remount the gear

I've used both epoxy and gorilla glue and think both work fine. The small holes are important to act as glue nails.
