I had this problem too, and I found that you can disable pretty much every kind of notification in the notification scheme in your project settings. I disabled notifications to watchers for any issue update and that pretty much solved my problem of having multiple people BEGGING me to stop spamming them with hundreds of useless notifications every time I triggered that option.
It would be nice to have control over email notifications when saving Advanced Roadmaps changes to Jira, in the same way that's possible with Bulk Edit.
At times, the changes are important and worthy of notifying folks. Other times, I'm just doing cleanup resulting in dozens of notifications which is at best, unnecessary, and at worst, annoying.
