Some people do it anyway, but it's among the least-safe things you can can.
I don't entirely agree with your response. If canning fat doesn't kill all the bacteria in the process, then that means that no food with any fat should be canned. Sorry, but you cannot get 100% lean meats and yet they still can it. I realize of course there is a difference between canning very lean mean and (near) 100% fat, but the premise is still the same. If you get the temperature high enough for long enough it will kill the bacteria. Fat or no fat. That is why different requirements for canning Tomatoes versus Chilli. Granted the higher temperature for Fats might not make the bacon grease (or other fats) as palatable though.
Also if the Fat is preventing you from getting a good seal, then you are doing something wrong anyway. Part of the canning process is to ensure that the top of your jars are CLEAN which might mean using a warm/hot clean rag to thoroughly clean it as well as ensuring your sealing lids are clean as well. I have even heard of people using Alcohol to clean the top of jars and then following it up with a clean rag/towel.
People can butter all the time even though the County Extensions and FDA don't recommend it. It must be possible, otherwise why would one be able to buy Canned Butter?
http://www.internet-grocer.net/butter.htm To be sure the ingredients in Red Feather Canned butter are Pasteurized Cream and Salt, so no other preservatives. So if they can do it why can't we. Same holds true for bacon. If they can Can bacon, (

Now, if you are going to can bacon grease (or butter or bacon) you definitely need to be aware of safety. I wouldn't use the "Oven Canning" methods as found on youtube rather I would opt for Pressure Canning. Obviously keep everything as sterile as possible (is that even possible with Bacon grease?) and expect that the flavor and/or consistency of the final product will likely change (which may make the whole effort a waste for you). I have canned butter, and I can tell you that it does alter the taste and consistence of it, but not enough to upset me at all
Lastly, I would like to say that before using ANY canned product, Commercial or Home Canned (or any product for consumption for that matter), You need to be cautious and follow a few common sense guidelines:
Make sure the seal is intact - If not dispose of itMake sure it looks ok (as best as possible as canned food often changes from it's fresh state appearance) - If not, dispose of it. Make sure it doesn't smell funny - if it does, dispose of it Taste a small amount, make sure it doesn't taste funny - if it does, dispose of it.
Safety is always relative. It's inherently not safe to travel in a 2000 pound bullet (i.e. a car) at 65 Miles per hour, but if we take care and follow some common sense guidelines, we will be ok. Same with canning ANYTHING.
Lastly, you should take care where you store it. Cool dry place out of light is ideal
