2013 Tundra oil change interval

Sorry, but I have to disagree. You wrote as if engine maker's were quality constrained by spin on filter companies. Not true at all.
Engine makers are "in the drivers seat" to build an over pressure relief and/or anti-drain back valve in their engine if they want to. It's totally up to them to spec a filter with or without those features. They can also spec whatever requirement they want and let the filter companies bid on it.
I had a vehicle with the pressure bypass built in, so the spec'd filters without it. The engine had a known history of the bypass not being reliable.
At least with a filter you can screw on a new one if there's a problem.

Filters are an off the shelf product. Most are used in a wide range of engines (and brands). For decades designers just pick the size that fits in the allocated space.

Dodge recommends 16,000 km between changes (10k miles) in the 5.7 Hemi, and that's on 5w20 dino oil. Not happening with me, I change it every 8,000 km (5000 miles) and it's plenty dirty enough for me. Oil and filters are cheap relatively speaking. Most of my miles are highway, very little idling time.
