SSearlyruntimes and its PR were introduced to monitor runtimes that
would occur before either the logging globals were ready, or in
development, before the debugger was attached

These have proven to be few and far between, and we now have proper TGS
side server logging to address it. Keeping it only serves the sole case
of local developpers runing into such issues, which is extremely rare.
