I agree it is sad it has taken so long to have a change. Hopefully it is the precursor of an overhaul, and not a simple threshold doubling, which would be bad (to remain only at this level of action).
The DHF has been around since the legacy chain actually. Probably since 2019. And only had one update shortly after its release and then I think one or two minor updates later on (like the possibility to reduce the price you ask without creating a new proposal).
