Ah, you said “to_when_alone” in the blog text but the file uses “to_if_alone”! Tricky. Also this page has hex usage ID mapping if anyone finds it helpful:

In Karabiner-Elements version 0.91.5 "Change caps_lock key to command+control+option+shift. (Post escape key when pressed alone)" is included as an example in complex_modifications rules.
So, the editing of the json file could be skipped:)
Just go to Karabiner-Elements/Preferences/Complex_ Modifications/[+Add Rule] and [+Enable] "Change caps_lock key to command+control+option+shift."
One important caveat for TouchBar users (and maybe others?) - the CMD-ALT-ESC combination to open Force-quit does not work anymore with KE, and the FN key may disable itself. No workaround that I know of for the first issue. For the FN Key, it seems putting your Mac to sleep solves the issue.
Apart from that, god it's good to have Hyper back.
Love the Hyper key. Used it for years before Mac OS took it away. Have one question about your instructions. It flows from the fact I am not a programer. I have downloaded Karabiner Elements and replaced the Karabiner config file in my Home Directory with your config file listed in your post. I want to make the "to_when_alone change. I see the to_when_alone entry in your config file, where do I place "caps_lock"
Finally do I need to add the Seil app?
