Thanks for voting and commenting on this issue. Your feedback is key to helping us understand how you use JIRA so we can continue improving your experience. We have reviewed this issue over the last few days.
While we don't have any plans to introduce generic support for renaming any system field, we are very sensitive to the feedback that much of the terminology in JIRA is unfriendly to non-technical users. We're actively exploring ways to alleviate this in the future.
It's important to understand that we rarely try to implement individual features from jira.atlassian.com, but instead take a holistic look at the problem and use feedback from the comments here and a dozen other sources of customer input to solve the core problems.
Please don't hesitate to contact me if you have any questions or feedback.
Product Manager, JIRA Platform
