support for parallel alt-roots?

[ѽ҉ᶬḳ℠ via Unbound-users]

Hi, from what I comprehend the current unbound syntax supports one root at a time, e.g. either ICANN roots or alt-roots such as OPENNIC, but not 2 roots in parallel. It seems currently not possible to have 2 root-hint files, 2 name . as auth-zone or 2 name . as forward-zone. To get alt-roots subdomains resolved alongside the ICANN setup is currently a bit cumbersome and a transfer of the alt-root to local is not feasible. Not sure what the future of DNS holds but is seems that with blockchain and such there might be some traction on alt-root and thus I was wondering whether there is any plan to support alt-roots simultaneously, if such is technically viable and would make sense? Something along theses lines: root-hints: "/file/path/to/icann_root.hints" + alt-root-hints: "/file/path/to/alt_root.hints" and auth-zone:   name: .   zonefile: "/file/path/to/icann_root" + auth-zone:   alt-name: .   zonefile: "/file/path/to/alt_root" and forward-zone:   name: . + forward-zone:   alt-name: .
