If I look at the times I’ve implemented dark mode — I see that the effect will be:

1. Less lines of code (seems like a good thing)

2. I will still need to use prefers-dark-mode for some of my changes.

Thus — the concept count is ratcheted up by 1 more thing, and no concept is taken away.

The “concept count” is ridiculously high already.

They’re spending money from an overdrawn account.

If you want to permanently increase the number of things that a bunch of people must learn, it has to have more value or power than this.
