It's all part of the station rework. They are going to use that space for housing.
Looks like the construction made the taxi stand temporarily unreachable, so this appears to be the solution they came up with.

Edit: Worth noting that on the north side of the station there is an underground car parking garage, so it's not like they have removed all parking.

I do think the accessibility of the station is quite well balanced though. It's pretty clear that bike and bus are the main methods by which they expect you to come to the station, with taxi and car as an option.

Counted 99 bikes in one row, for a total of 10 rows and 4 partial rows.
So I'm guestimating about 1200 bikes
