Credit Where Credit's Due

Why do we lose our participation for FATEs when we accept a queue or die and take the return? I honestly don't understand this. I can finish a boss fate and accept a queue when it dies but if I don't wait for that visual completion notification, I don't get credit. I die in the Eyes fate, but because I took a return to Quarrymill, I don't get credit if I don't make it back before death.
I would be fine with going to an NPC to pick up any unclaimed xp/gil/gc seals as they give me sass for "having more important things to do." I just want credit for my participation.

"Aye, you may have left the finishing blow to another adventurer, but you spilt your blood too. Take what you're due and git."

You actually do retain credit if you can get back into the zone as it finishes.
It's likely a technical limitation keeping it on a per-zone basis.
