Perhaps most do but I see a different trend these days. "The network" is a lot more important now since so many things are cloud-based.

Our networking group automated a deployment for the fix and contacted everyone that has ever bought an ASA from our company and updated them. We have ~400 ASAs across the country still have < 50 to go. There are still a few stragglers and the older ASAs need a bit more TLC.

Many of those clients have a maintenance agreement with us that includes these sorts of things and changes. All of them were updated and tested within 24 hours.

We did the same thing for the Juniper exploits (albeit we only had a handful).
