adding an option to timeout subscriptions

Is there a way to configure the table to stop subscriptions after a set amount of time?
My site is small, but serves as a frontend for a database that is constantly updated (every second or two, multiple times).

If a user stays idle on the table with a hundred results displaying, those results will keep on subscribing to the database collection, causing a lot of unnecessary traffic that impacts performance.
I see that there is an option to throttle the refresh, but the issue still stands regarding the subscriptions still being active.
Is it possible to kill the subscription after a set amount of time from within the table?

The issue does not name any files, tests, or entry points. Start by locating the table subscription lifecycle and the existing refresh-throttling option; done would mean defining and implementing a configurable timeout that stops idle subscriptions without disrupting active table use.
