I'm wondering if you can describe your case, which you write as ETTH. The deployments that I've done to date, ETTH has either been GPON (so we have a CPE device just like cable), or we the customer comes in aggregated on a VLAN, so in fact the switch at the data centre annotates the DHCP request when it relays it.
When you say "annotates", do you mean "option 82"? In that case, yes, this is done here as well, but if the customer powers off their device, the DHCP lease is not invalidated.
Deployment cases are ETTH as in "L2 switch in the basement connecting the customer apartment" and DSL as in "L2 dslam and L2 bridging modem" (or modem doing "hybrid", ie IRB). In neither case the DHCP lease is invalidated when the customer access link goes down.
