Hello everyone,
After reviewing the handler logic, I am not clear that it implements logging
within the pattern guidelines defined by the base logging implementation.

In log.py#L103 
<https://github.com/sqlalchemy/sqlalchemy/blob/c2cad1f97c51c8a2a6ad5d371ece7bcd9c7ffcf9/lib/sqlalchemy/log.py#L103>,
 
the level and existence of at least one handler are checked.

I only have a handler added to a root logger that I don't control, and we 
rely
on ancestral propagation.

The concern I have is due to any IO emitted to the console streams breaks
the calling code that I don't control. With this pattern, I have to 
preemptively
add null handlers to every logger, and if I miss one and it manifests in 
production,
I'll have a problem.

Anyone have any thoughts around this?

Thanks,
jlc
