Do what works for you. I love bacon, but I also love eggs, pork, beef, duck, liver, goose, etc. too much to go just bacon. I can tell you, however, that bacon and cream cheese is a delicious combination, so go for it, if you feel like it. As long as you keep your carb intake low, you’ll be fine.
A lot of this stuff is just a gimmick to get people to mix up their thinking about what’s okay to eat. Many people come to these forums with a real phobia about fat, the product of decades of brain-washing. The idea of eating nothing but bacon, which is both scrumptious and fat-laden, can entice such people into a different view of fat. (On the other hand, we do also see people who have the idea that a ketogenic diet is about cramming in as much fat as possible, to the point of vomiting, and that idea also needs to be knocked on the head.)
The only real keto rule is to keep carbohydrate intake low enough to experience the benefits of lowered insulin levels. The rest is just tweaks. Or fun, like eating bacon!
