Btw. someone mentioned "Voting" on JIRA tickets.
We never really used it, but instead of a Doodle or endless email threads
for decision making on a fine grained level like adding or removing a
method, it could be best if all java.net users (every EG Member should also
have an account I assume;-) could use JIRA and vote on such tickets.
For the sake of transparency all relevant GitHub tags like
https://github.com/unitsofmeasurement/unit-ri/releases/tag/0.7 (for EDR)
contain a pointer to JIRA sprint reporting. Thus if some tasks contain
votes, that's also visible to everyone who reviews the JSR, be it EC or any
other community member.

The javadoc does not explain how the "health" system of units is defined.
