+        Thank you for taking the time to file this issue.

+        Please note that rnx-kit is still in the early stages of development.
+        We are hard at work, adding new packages and features on a regular basis.
+        We welcome your feedback in this bug report. Given our focus on building
+        out the first "complete" version of @rnx-kit, supporting external users is
+        not currently a high priority, so we unfortunately cannot guarantee prompt
+        responses at this time.
