Cisco can screw (and likely will) the commercial Enterprise offering, not really the Cilium project
Those big companies are inconsistent so you can’t count on that, especially if the change doesn’t affect them or they’re already maintaining an internal fork. It’s not mission critical for them so I would not be shocked if they decided that some other approach was best for their businesses and their engineers spend time migrating instead of taking over maintainership.
I’m not saying that will or even is likely to happen but I would think about how hard it would be for you if it did because the odds of Cisco screwing up a popular project are a lot greater than zero.
