This has been known for months now. The only promise was that you will be able to colonize the system solo within the 4-week limit. If you are going to do it solo, you'll have to do some work towards it.
Solo, by the look of it, CMDRs should choose to build an outpost as, allegedly, the commodities needed can be carried on 1 FC.
Building a station with a large pad (which makes sense for hauling) is going to be a major undertaking, particularly with some commodities only being available in small numbers with a slow respawn.
I'll see if I can complete my claim in the 4 weeks I have, being retired I can spend more time than a working player, just playing the game.
I suspect I am going to fail if the goalposts are not moved in my favour. But it will be fun trying.
