Hello Slf4j community,

I'd like to share a happy discovery about the well-known "Log4shell" vulnerability on Log4j2.  Apps that use Slf4j with Log4j2 backing (and which don't otherwise call Log4j2 directly) can be mitigated by log4j2.formatMsgNoLookups=true

As I write this (with Ralph having yet to respond to my follow-up), it's not really some final determination but it's highly encouraging.
