It's just another trend to have wooden floors in the kitchen and dining room.
Well, define trend. We've had it in the rental apartment for 8 years already. [emoji6]
Tiles in wood look - for God's sake, that would be my personal nightmare. But, as you already said, it's all a matter of taste.
I can't understand the maintenance and oiling argument. The claim that you have to re-oil once a year isn't really true; you can do it, but it's not absolutely necessary. Such industrial parquet is quite robust and durable, and it's no coincidence that this stuff is often installed in commercial places with heavy foot traffic.
In a private setting, an oiled wooden floor definitely has advantages. If there's a scratch, you can quite easily repair it locally: fix the spot with sandpaper, a bit of oil on top, good as new.
But sure, it has to fit personal preferences and the context. But basically, wood in the kitchen (even in the bathroom, although I wouldn't do that either) is an equally valid flooring option. If you want to leave water standing on the wood for hours, it can cause stains. But seriously, who leaves water standing on the kitchen floor for hours?! I find that contrived. In the entrance area, where wet shoes might stand around longer, understandable, but in the kitchen? The stuff is oiled (i.e., saturated) or sealed, so nothing soaks in that quickly.
