DDNS TTL in 4.3

In 4.2 and previous it was true that the TTL sent for DDNS requests was 
1/2 the default lease time. In 4.3 it seems that there is no TTL value 
sent, so the DDNS records simply inherit the zone default TTL. That's 
not necessarily a bad thing, but it's different, and I need to know how 
to advise my customers if it turns out they were depending on the old 

Where can I find documentation on this change? And if it was discussed 
previously, my apologies for missing the memo.
