I'd go further: for many games the right thing to do is pause execution entirely if the window is minimised or the user switches to another tab or application. Obviously not possible for online multiplayer games, but a good practice for single player.

Rendering can be but isn't always the most expensive portion of a game's execution, but if you have a lot feeding into that in terms of object updates and game logic you can find yourself chewing a surprising amount of CPU time, and therefore power, which isn't great if the host device is running on batteries.

Please have this setting be configurable if you do this. I hate when games pause when I alt-tab to another window on another screen while I'm waiting for something to finish in a game.

For many games, idle games are a special case though, I don't think anyone who plays an idle game would want the logic loop to pause. They typically take a long time to play so minimizing and checking back every now and then is a very common thing.
