Yes, it is definitely a good feature. It's part of their security architecture. They figured out a way to allow developers complete freedom in distributing their software directly / outside of the App Store while still offering users protection against malware.
The point of the killswitch is to disable malicious software that someone tricked you into downloading off the internet and installing. That is the only thing it would be used for (and I'm not aware if it ever has.. maybe because it's a good deterrent).
It is not the same as the broader App Store approval guidelines. This is specifically for disabling malware, e.g. a bad actor tricking 10% of Hacker News into installing a malicious fork of brew.
I also want to make it clear I have no reason to believe this developer is anything but trustworthy. I just am curious why they decided not to sign it.
