This looks like an interesting idea, especially on top of JUL which sucks a bit (but is a standard now). One thing I would recommend is benchmarking on the front page. This looks like something that has some overhead. e.g. the list syntax. I suggest doing several overhead benchmarks to quantify the overhead/saving with various VMs/logging configurations.

Here are the benchmarks [1] using a no-op appender. There are some micro-optimizations I can make, but I think this is a pretty good start.

I'll add that. I do have the benchmarking from Blindsight, the Scala logging API, and it's on the order of nanoseconds:
