It doesn't hinder the expansion of Wikidata because the current types are flexible. Added types will improve performance and simplify client access for some scenarios, but every scenario I can think of is possible with the currently available types. If you have data that you would like to enter, I suggest doing so and then you can switch some properties to the new types when they are added if you want. The three types currently supported for properties are lists of items, media, and strings. You can group different types together for a single property by creating a new item to hold them. Soon you will be able to add an extra property that can be used to differentiate values in a list, called a qualifier. Other types are coming, but for example, if you want to use a date now you can just use a string and then parse it into a date on the client-side.

Contrats! Anyways, I still miss various data types to be available for properties - unavailability of these greatly hinders the expansion of wikidata database. Any plans on how fast new (and comprehensive) data types will be introduced to
wikidata.org?
