No, not at all, you very rarely want to change LD_PRELOAD and

My conclusion is we don't agree mainly on this:

I think there are cases where you want runtime configuration to
propagate or be set more or less globally. You think no one will ever
want some runtime option to propagate.

The rest of the argument is based on that difference.

Also, I don't have much of a problem with having command-line options to
configure the runtime too, although I think in linux/unix is much less
natural. Runtime configuration will be most of the time some to be done
either by the developer (in which case it would be nicer to have a
programatic way to configure it), or on a system level, by a system
administrator / devops (in which case for me environment variables are
superior for me). Usually runtime options will be completely meaningless
for a regular user. Also, will you document them when you use --help?
Will you omit them?
