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.

Hi ASDF list,
I have some huge generated Lisp files which took a lot of time to compile into fasl files. I put the sources into my ASD system definitions with other hand-written Lisp files in parallel (thus no dependencies at all).
I found that, whenever I changed the ASD definition, if I load the system by ASDF:LOAD-SYSTEM, all Lisp files will be recompiled, even their source files are not changed at all.
Is this a desired feature or possible issue? Do I need to provide sample code to show this “issue”? I’m using quite a recent ASDF (version: 3.3.1.7)
