Drivechain bips effectively firewall mainchain from any nonsense ont he sidechain and consolodate the attack vector to miner theft. It locks the drivechain funds in a special wallet with no priv keys and to avoid miner theft it takes 3-6 months to withdraw from the sidechain. Its basically the major "flaw" imho its too secure i think probabalistically the 2 week escrow works fine but everyone shit themselves so paul bumped it up to 3 months... Script wise it is relatively simple (im not an expert but if i can understand it its pretty simple) it is commonly argued whenever we get a drivechain, ctv, recirsive covenants or anyprevout upgrade we should just stop for a while bc at that point scalable drivechains are possible(with any of the upgrade, drivechain is the most limited) If we dont get drivechain we might get some more complex covenant thing which i personally dont trust

Rootstock is 2/3 the size of lightning and caters largely to users in countries where holding USD is difficult or illegal. It generates over 1 btc in txn fees every month paid to btc miners. All of this is besides the point that drivechains allow for far more than a Bitcoin native EVM. Just be proud as a bitcoiner your node is helping secure the savings for marginalized communities out there! (Check the most recent coinbase for RSKBLOCK it's already merge mined)
