We need to make a single report for this so that people can vote on it. Here is a summary of related issues I found:

~~EJB-14~~ - suggestion to add nullable to @Embedded
~~HB-31~~ - pretty much the first issue on this topic, closed by Gavin (3 votes, 10 watches)
https://issues.jboss.org/browse/HIBERNATE-50 - great discussion, wrong JIRA (12 votes, 13 watches)
HHH-3733 - suggestion for a new annotation (3 votes, 5 watches)
HHH-4874 - bug report on the behavior (8 votes, 10 watches)
HHH-7610 - improvement request (5 votes, 4 watches)

We should focus on just one (either HHH-3733 or HHH-7610) and vote it up. The rest can be probably closed as duplicates.
