I never had this issue with my kids (or relatives ones), but understand the concern.
By the time I built something really robust that did not cause as many problems as I might be trying to avoid, I always bought some extra drivers. Whether you build grilles or not, I highly suggest doing this for DIYers. You never know when one or more of the drivers goes NLA. For something like the 1099s, this is pretty inexpensive too. It is good insurance for potential driver “accidents” too...
