Character generation now has an option to auto-generate a description and intro. Pets and horses already have a randomized intro, but could the auto description system be adapted for retainers, pets, and mounts?
It'd help give some inspiration or something to build on for writing a more detailed description, or otherwise just add more flavor to the game than the current bland defaults which are often left as-is. Many, perhaps the majority of horses I see still have a standard description like "This is a common horse, bred as a mount."
Retainers like guards have a better default description, but I'm not certain if they're randomized or not.
