Just to clarify, the main upside is for searching purposes, right? To be able to filter by only these unknown/unnamed hybrids and exclude hybrids from genus searches?
If the hybrid genus taxon is “below” the rank of genus, it’ll still appear in typical searches for observations in that genus. And from a “Needs ID pool” management perspective it would still require people to know to mark the Community Taxon as not needing improvement in the DQA (or are you proposing it be treated the same as species rank in that regard?)
In either proposed system – separate taxa for hybrid bin genus taxa vs. a hybrid checkbox, would a “normal” genus ID ever count as a disagreement with a “hybrid” genus ID?
And as far as “@bouteloua and I think this would be feasible within the current system (i.e. no changes to the code needed” just a clarification that I’m not personally supporting this at this time.
