It’s nice to have, but it doesn’t take into account synonyms and different wordnforms, as far as I understand. In many non-English languages that would be a huge problem, but even in English what would you do in the goose-geese situation? Or any plural at that point.
You might suggest avoiding using plurals, but a) I came into Obsidian for flexibility, not to have to second guess myself on every word, b) there are a lot of situations where it isn’t possible, especially if you’re not writing in English.
There is also a problem of words with the same spelling, which seems completely insolvable this way.
So, in conclusion, yeah, it’s another one of workarounds, and not a bad one—and thank you for that—but it is still far from being perfect.
