It was initially on purpose that I inserted this restriction, because I felt that 1- there was no clearly good default that I could see. 2- if such a default is identified, we can enable it later. 3- if no default is initially provided, we can provide one later with backwards compatibility; but if we provide one, we can't change it with backwards compatibility. 4- I'd rather error out early with an annoying error message than do something silently that will be the wrong thing for many users.
Do you really think there should be a default? Which, and for what reason? Is there a compelling reason to think that everyone will agree to same default?
After actually using the configuration system, I came to the conclusion for the sake of simplicity, ASDF should always inherit configuration, that :inherit-configuration and :ignore-inherited-configuration should not exist, and be replaced with a function such as, for example: asdf:initialize-source-registry-from-defaults &rest conf-sources by default, upon initialization ASDF would call (asdf:initialize-source-registry-from-defaults :system :user :env). Users could override that in the initfiles if needed. The reason for this is that I want users who install distro-provided packages to be able to start and use ASDF2 without having to create a local configuration file. OTOH, people who don't use distro packages wouldn't care about inheriting the system configuration because they wouldn't have it, so no harm done -- Stelian Ionescu a.k.a. fe[nl]ix Quidquid latine dictum sit, altum videtur. http://common-lisp.net/project/iolib
