IMHO this would be yet another parameter that can be voted by shareholders ON-CHAIN!!
I agree that this is something that should be parameterized.
Those who are "lazy" should nominate a proxy and those voting by proxy should never have their votes expire unless the proxy stops updating.
This way you can serve those who want it to last forever and those who want it to expire in a manner that ensures that all voting is "pro-active" and that "passive" votes go with the majority of the active votes.
I agree with no expire on the proxy front.
Those that are non-proxy IMO should be voted on a quarterly basis, with a 1 or 2 week reminder that the wallet can signal to the user that their vote is coming due for an update decision. If no action is taken, then either their vote is completely taken off books or quickly degrades over time by like 10-20% per day.
Most companies do quarterly updates/reviews and so should non-proxy voting.
Or you could go hockey style and do 3 voting periods throughout the year.
Just my 2bts!
