We've recently received some commentary through other channels, so I thought I would provide an update to reiterate our position on this issue.
JIRA's voting system was initially designed for cases where JIRA served as a public bug tracker or feature request management system, like jira.atlassian.com or issues.apache.org/jira.
As JIRA has matured, we have focused more and more on teams using JIRA for internal software development. Voting provides a useful way to capture quantitative feedback when your issues are public; however, it is not intended as a way for small development teams to prioritize their work.
We recognize that everyone uses JIRA differently, and that not having this feature makes it more difficult for teams to implement a strict prioritization-by-voting process with JIRA. However, our current focus is on improving the usability and performance for teams planning using components, versions, backlogs and boards. In short, additional functionality for voting is not a priority for us for the foreseeable future.
