I've only had the 4R for a year and less than 10k miles, so my experience with the plastic oil filter housing and internal filter is European cars, not Toyota. I had no problems with the oil filter housing on my Audi for almost 12 years and 125k miles, which is decent for an Audi but just breaking in a Toyota. At that point, the oil filter housing had warped slightly, causing a leak between the block and the assembly. It was well known that replacing the gasket would be a short term fix, so replacing the full assembly was the only true fix.
I've seen more inline oil filters collapse than the external screw on, so to me that would be the bigger concern.
