sounds reasonable. at very least, better than nothing.

in the absence of a standards-based solution, any options for hooks in bind to external scripts, even if ad-hoc?

e.g., "if when change in DS Record in local bind, then fire this external script which will manage the DS submit/withdraw via API to registrar"

a completely de-coupled solution, independent of bind itself, is doable -- but again, ad-hoc, and seems a step backwards given the nice progress with dnssec-policy/kasp simplifications in recent versions.

if that's all there is, know of any existing, proven ad-hoc solutions?
