I've gone ahead and [crafted a PR|https://github.com/apache/flink/pull/27650] 
that I believe should address this. It looked like the previous behavior was 
explicitly capping the precision level for the timestamps at 3, whereas this 
proposed update would remove that restriction and generate a corresponding 
`TIMESTAMP_WITH_LOCAL_TIME_ZONE` instance.

I'm not sure if there are any additional places where we would need to make 
these changes or related documentation, if necessary. I've added you as a 
reviewer and would appreciate any feedback or guidance if you get a chance.
