+### Non-HTTPS repositories
+
+A repository URL doesn't have to be HTTPS - several modules automatically adjust the tool's configuration so
+the plain-HTTP repository is actually usable, instead of silently producing a config the package manager
+would refuse at run time:
+
+- `python`: pip gets the repository's host added to `trusted-host`.
+- `php`: Composer gets `secure-http` disabled, and `packagist.org` is disabled alongside it (an HTTP source
+  implies a private, non-internet setup where the public registry wouldn't be reachable anyway).
+- `nuget`: the source gets `allowInsecureConnections="true"`.
+- `java`: SBT's resolver gets `allowInsecureProtocol` appended. **Leiningen is the one exception**: its
+  standalone launcher refuses any non-HTTPS repository unconditionally, with no configuration able to change
+  that - a repository configured here simply won't be usable from Leiningen specifically.
+- `go`, `rust`, `apt`, `apk`, `yum`: no adjustment is needed - these already work the same regardless of
