Grant's 1993 Bridgestone RB-1 had a 54mm trail with 25mm tires. The 2022 Roadini had a trail of around 58mm but with a 5mm lower BB. The Cheviot (I can't find numbers for the Platypus) had a trail of 58mm with a 25mm tire (but obviously few people would run 25mm tires on that bike), but even with a 33mm tire it'll still be a 61mm trail, making the bike steer a little slower but still agile. I had a custom bike built around the 1993 RB-1 geometry with a lower BB, and it rides similarly great. Now when it comes to compliance, stiffness, etc., the tubing thickness etc matters more, but in terms of handling I think Grant has it dialed down and you can see that he pretty much keeps all his bikes in the same zone when it comes to trail. The longer wheel base that he's been going for recently adds alot to stability and high speed handling at the expense of packability into bike boxes, which few care about. If you were to buy say, a Craig Calfee carbon framed bike, it actually has a very similar geometry too the RB-1, and rides similarly, but of course being made out of carbon and with a short wheel base and relatively little tire clearance chances are that bike wouldn't appeal to the same people who like Rivendell bicycles.
