Have these changes been tested with the APM? I grabbed the latest from HEAD last week to work on upgrading our instance and my experience (tested twice) is that the SQL upgrade files are no longer being sourced. I backed out the changes to packages/acs-bootstrap-installer/tcl/30-apm-load-procs.tcl and the files were sourced as they should be. I haven't had time to examine the changes in detail yet as I'm focused at the moment on our upgrade. Just wanted to report back that there appears to be an issue.
