ASDF recompile all files if ASD file is changed?!

[Robert P. Goldman]

Yes, this is a feature, not a bug. If you change the ASD file, ASDF has no way to know whether any compiled file in the system is up to date. For example, you could have added a system dependency that brings in a new use-package relationship and a macro, or reader macro that invalidated every compiled file.
