Commented Issue: anonymous users for simplemembership provider [384]

dear team,

i would like to suggest an improvement for simplemembership provider. I checked the http://msdn.microsoft.com/en-us/library/webmatrix.webdata.simplemembershipprovider(v=vs.111) msdn library and no method allows to create an anomymous user that later can be transformed-when user register - in a full user account. I believe this is important because it helps to store data - language, country, currency selection, cart and more - in a database to display customized information while this user has its first impression of the site.
my idea is to include a method + a unique identifier to store cookie information that later can be fully transformed - using that info - to a full user account details when user register.
brgds!
sebastian.
Comments: thanks for the reply. just to confirm?, a new security system.. so simplemembership will not continue as the default security system in templates as its shipped now with mvc4?. any paper or post to check technical characteristics or ETA for that system?, thank you so much.
