Taking too narrow a definition of zettelkasten is antithetical to the combinatorial creativity inherent in one of the zettelkasten's most important affordances.
OP was right on track, perhaps without knowing why... I appreciate that you scratch some of the historical surface, but an apple/tomato analogy is flimsy and the family tree is a lot closer. Too often we're ignoring the history of ars excerpendi, commonplacing, waste books, summas, early encyclopedias, etc. from the broad swath of intellectual history. What we now call a zettelkasten evolved very closely out of all these traditions. It's definitely not something that Luhmann suddenly invented one morning while lounging in the bath.
Stroll back a bit into the history to see what folks like Pliny the Elder, Konrad Gessner, Theodor Zwinger, Laurentius Beyerlink, or even the Brothers Grimm were doing centuries back and you'll realize it's all closer to a wide variety of heirloom apples and a modern Gala or Fuji. They were all broadly using zettelkasten methods in their work. Encyclopedias and dictionaries are more like sons and daughters, or viewed in other ways, maybe even parents to the zettelkasten. Almost everyone using them has different means and methods because their needs and goals are all different.
If you dig a bit you'll find fascinating tidbits like Samuel Hartlib describing early versions of "cut and paste" in 1641: “Zwinger made his excerpta by being using [sic] of old books and tearing whole leaves out of them, otherwise it had beene impossible to have written so much if every thing should have beene written or copied out.” (Talk about the collector's fallacy turned on its head!) As nice as Obsidian's new Web Clipper is this month, it's just another tool in a long line of tools that all do the same thing for much the same reasons.
Ignoring these contributions and their closeness means that you won't be able to take advantage of the various affordances all these methods in your own slip box, whichever form it takes. How will you ever evolve it into the paper machine that students a century hence are copying and mimicking and pontificating about in their generation's version of Reddit? Why couldn't a person's slip box have some flavor of an evolving encyclopedia? Maybe it's closer to Adler's Syntopicon? Maybe something different altogether for their particular use?
