> On most databases, we no longer need ValueObjectTypes for java.time classes, as demonstrated by CAY-2701 for modern MySQL (also see https://dev.mysql.com/blog-archive/support-for-date-time-types-in-connector-j-8-0/ ) :
> {noformat}
> rs.getObject(i, LocalDateTime.class);
> st.setObject(pos, val, type);
> {noformat}
> So let's make the approach in CAY-2701 the default in Cayenne, creating the appropriate ExtendedTypes, and then check which databases DO NOT support it, and create custom ExtendedTypes for those. 
> Of course, as a result MySQLLocalDateTimeType will no longer be needed, superseded by  the standard one.
