Almere obviously doesn't have a whole lot of history compared to other Dutch towns, it is quite literally built on 'new land', areas that were turned from water into land in living memory (1950's and 1960's). Almere 'haven' is the oldest part, subsequently Almere has grown in jumps to become the fastest growing and now the 7th largest municipality of the Netherlands.
So this why Almere is the place in NL where there is room for such experimentation. In other Dutch cities it is usually super crowded already and the only places where you can still expand is at the edges, and municipalities tend to be very conservative to help the new areas blend in with the older ones.
I have some family living in Almere, they work on the other side of the bridge so over the years (they have lived there now for 35 years) that took up a lot of commute time, but where they live is child friendly and it is a much nicer house than they would have ever had anywhere else in NL on a much larger lot. But there isn't - even today - a whole lot of life in Almere compared to other Dutch cities and likely this will remain until it is so old that it no longer stands out as the 'newest city'. Second generation citizens of Almere already are much more at home there than those that moved out from Amsterdam (and especially from Bijlmermeer), and with every passing generation that will improve.
But it will be a long time before people will go to Almere to see the city center.
What would really help Almere is a second bridge into Amsterdam but there are many reasons why that likely will not happen in the next 20 years or so. (see: https://nl.wikipedia.org/wiki/IJmeerverbinding (Dutch)).
