Barebones is the key word here. Minimal functioning product.
Yep. It's like they built a house and now the residents move in.
The house looks great, the materials are of premium quality, everything is polished and very tastefully done. But when you spend a little more time in there after the initial room tour, you notice that there are only floor lamps everywhere, but no ceiling lights, because obviousely there was no time for proper electrical installation. Then you realise that the beautiful view of the garden is only a photorealistic picture glued onto the windows and some walls are only made of cardboard with a pretty wallpaper on top. Also, some doors are locked and when you spy through the keyhole, you see the outside, because there are no rooms behind them. At least there is a fireplace... but wait, that's just a HD TV running a video of a fire, built into a chimney.
So, you have a house, yes, and clearly you can live in it, so it works as advertised. But that's it, otherwise it's full of placeholders and unfinished work and is in reality still a construction site.
And then the architect tells you, that this is exactly the house they wanted to build. Seriously?
