I totally forgot about that :P That would be great indeed.
The PD trigger board may be much more involved/expensive though and I have not seen any budget battery banks supporting it. One can dream.
I expect consuming devices to adapt themselves to the three or four commonly provided voltages for the foreseeable future.
You shouldn't eat candy given to you by strangers. If you're in a large group and someone knows the candy, maybe. Code is food for your computer. Be wary. Our large Open Source group of friends has learned about many kinds of candy and shouts loudly when some in the group becomes ill. You don't want to become ill. Some risk exists, but with a large group it is generally ok. Don't install packages as root, don't install what you don't need.
I run my frontend builds through Docker (also during development). By isolating access to the host system to the files/folders necessary for development I've shielded off the majority of current realistic attacks I've seen as NPM based exploits. I'm certain the approach can be replicated for other frameworks, but we use Ember and docker-ember. I doubt it runs as smoothly on a non-Linux OS.
