Okay, the question was time line. I hope Unbound designers answer with 
an outline for time and design considerations. Whether a month or a 
year, some short term workaround may be useful. All workarounds (adjust 
cache and prefetch) are imperfect but may get by short term. At some 
reasonable cache rate, TLS connections will likely expire anyway before 
fresh data is needed. Neither server nor client will want excessive 
dangling connections. The gap in behavior may not be as big as it seems.
