Legacy behavior, since retry was added later...

Sounds fine, just add it to the doc.

Sounds rather annoying. We could combine these: if no retry was configured, 
give the warning and use a default of 1 hour. Have to ensure that the default 
setting doesn't persist in cn=config, so that it will keep warning until an 
explicit value is set.

Sounds fine, but unless you can add these quickly I don't see any reason to 
hold 2.4.13 for it.
