You can see how that is next to impossible, though. You need to test in millions of phones over several years to verify that something is good. Which means it has to get into production. But that isn't allowed. A Catch-22 situation.
If there's some other connector that looks compelling for charging and data, phone makers can get together and adopt it, too. We don't need phone-specific experience or to have done an A/B test with tons of statistical power.
USB-C ain't perfect. But it's pretty tough to beat. There's also room for incremental improvements in reliability and functionality within the standard, too.
At some point, just living with something as the standard is the way to go-- rather than hoping something new will be worth forklifting all the infrastructure and/or splitting the market.
