I have likely missed several points but overall it seem pretty
clear to me that all requests / concerns have not been addressed
and this proposal is not yet ready for another round of review.
Also x-post from GitHub PR of my personal nitpick:
"... have noticed that all logging functions have
file/line/function data as template parameters. This will create
insane symbol bloat. While I can understand desire to use some
nicer variadic argument API providing at least one log function
that it simplistic but moves all compile-time data to run-time
default argument is absolutely necessary for me to consider this
viable."
