Adding a snippet from Kirb in that thread:

I think that [HBDebugLog logging in non-debug builds] was intentional, because the performance of making debug logs with os_log is negligible
whether it matches what users expect, for those strings to not be compiled in, maybe not, though

Building on that, Apple includes debug logs in release builds, including for systems that are not relevant for developing user applications.

Even though I personally believe it is best practice to include debug logs (using the os_log system) in non-debug builds, Kirb's point that code may be compiled into a distributed build that would not have otherwise been due to using a different SDK version or minimum deployment version seems confusing.

In the referenced Discord discussion, Kirb also showed his support for this change.
