Just a heads up, it seems like this PR introduced a regression that for now
we only seem to have reproduced in DataDog's systems. I'm unsure about how this
PR introduces it, just verified that reverting it fixes the issue.
The error we are seeing looks like this:
```
Error: type_coercion
Schema contains duplicate unqualified field name
"foo(bar(tags,Utf8(""baz"")))"
```
I'm still trying to create a minimal reproducer in this repo.
