I currently work for Riot Games and have a background in operations, networking, system administration and was an early MongoDB employee. You can find me in all the usual places, but probably the most useful and relevant are listed below:

comment With 3 production nodes, why Mongodb complains about even voting nodes?
It depends on your implementation, but votes are involved when deciding where a write on your replica set has made it to. Take the w:majority concern for example - that makes sure a write hits the majority of nodes in your set (in your current example, that would be 3, but with one on delay it has to hit all current nodes). Hence, removing votes can have unintended consequences. Similar mechanisms are used in migrations (sharding). Basically I talked with the engineer that wrote the replication code fro MongoDB and her advice about changing votes was: "don't do it, it's messy" :)
