[Message part 1 (text/plain, inline)]

Unless you’ve set package-native-compile to t so you’ll rarely see this buffer. Installing new packages is not a frequent operation in normal Emacs usage, and when a user installs a new package and loads it, he’ll expect that buffer, not when simply having a package that requires that a package.
