Tasks set to manual automatically run on upgrade

I had a task 'Rebuild Repository Browse' in 3.7 set to manually run and upgraded my instance to 3.21.1. I noticed when I did this the task ran on upgrade. At first I thought the date may have just updated in the UI, but I saw the respective log message:

2020-03-20 17:40:57,905-0400 INFO  [quartz-5-thread-3] *SYSTEM org.sonatype.nexus.quartz.internal.task.QuartzTaskInfo - Task 'rubygems' [create.browse.nodes] state change WAITING -> RUNNING

This had minimal impact to me being just one task, however, I can imagine this having huge impacts on upgrades with many manual tasks (perhaps some set to preserve them but not run automatically, some repair, etc).
