I get your points, but the purpose of the list was to show that the male romances fall short in every aspect. Otherwise the list would be balanced. I expect each option to be different and interact differently.*snip*
Judy's side quest structure is similar to River's, but it works for Judy because she was included in the main plot and Judy/V bond over shared losses from the Heist. It becomes the foundation of their romance. Panam doesn't quite make that bond, so she got the gradual buildup with more scenes throughout the main story and her side chain. No such compensation for River/Kerry.
If you only consider how River/Kerry are fleshed out at this point, you can make the argument that their detachment makes sense. But who wrote their stories like this? It gives the impression that their neutral/non-romance content was written without consideration or influence of what the romance arcs would become while Judy and Panam were woven in throughout V's story. It does not feel like their romance content was considered in parallel throughout their development to ensure all players could enjoy a similar experience. It feels like their content was squeezed in however it would fit once everything else fell into place and the result is not at the same level as Judy or Panam.
