The topic is about idempotency though, and what you are describing is not idempotency. You are describing something different, and arguing “but it accomplishes a similar thing.” It appears you have come to the same conclusion as the article that building idempotency isn’t trivial.
Proprietary techniques like this are usually a good indication you’re missing something. In this case it sounds like you are missing appropriate validation of the issuer and/or token itself.
Like the one where 1.5T in value went pfoof due to reasons you mentioned? I will let people judge whether your arguments are most likely, or whether this is bubble syndrome. Hint: there is a large distance between use of smart pointers and market effects.
Gigabytes even (people do the silliest things). But ‘find’ gets me there 90% of the time, and at that point the amount of vertical scrolling isn’t really any different than in a 2kb file.
Love the spirit, but the attack-plans example IMO looks worse with this formatting. I don’t love the horizontal scrolling through properties of an object.
