There’s a Wikipedia page for the hamlet, but it’s empty. No population data, etc.
I’d much rather see no data than a LLM’s best guess. I’m guessing a LLM using the data would also perform better without approximated or “probably right” information.
Checking again for m-xylene, https://m.wikidata.org/wiki/Q3234708
You get physical property data and citations.
Now compare that to the chem infobox in wikipedia: https://en.m.wikipedia.org/wiki/M-Xylene
You get a lot more useful data, like the dipole moment and solubility (kinda important for a solvent like Xylene), and tons of other properties that Wikidata just doesn't have. All in the infobox.
It's weird that they don't just copy the Wikipedia infobox for the chemicals in Wikidata. It's already there and organized. And frequently cited.
Maybe it's more useful for other fields, but I can't think of a good use I'd get from the chemical section of Wikidata over the databases it cites or Wikipedia itself...

The cost of now having unknown false data in there would completely ruin the value of the whole effort.
The entire value of the data (which is already everywhere anyway) is the "cost" contributors paid via heavy moderation. If you do not understand why that is diametrically opposite of adding/enriching/augmenting/whichever euphemism with LLMs, I don't know what else to say.
