I forgot to mention the issue where one set of patches are updated earlier than another. That doesn't seem to be the case nowadays as they seem to be updating simultaneously but in the past, this was a big sticking point as fusee patches tended to be updated earlier than Hekate patches. There are also situations where Hekate or fusee/Atmosphere get updated before the other one leading some people to think there is an issue with the patches rather than the bootloader.I think point #2 goes more towards people just using one package to avoid confusion.
It doesn't necessarily mean they'll use both Hekate & Fusee, but rather, by having all the sigpatches for both in one pack, they can use any of the two boot methods, since one sigpatch method doesn't affect the other and they can be interchanged.
That way we might get less issues of people using the wrong pack while they are booting with the contrary payload.
Still tho, the bottleneck of the issue is Tinfoil at the end of the day.
What I'm trying to say is that it is impossible to make something idiot-proof but what you can do is educate as many people as possible so that in turn they can educate and help others when problems arise. In the entire history of patches, there has never been a thread or package with both sets included. Personally I would like to keep it that way to prevent as much confusion as possible. I also would personally like everyone to move away from the term "sigpatches" but unfortunately we don't always get what we want.
