findInstance() not generated, what is the "new" way of doing this ?

Using Nb 8.2 Wizard to create a new TopComponent I see that the "findInstance()" method is not created anymore linke in older versions. I understand we want to allow for Singletons as well as non-singletons, but 
1) Is it still practice to create a method "findInstance" ?
2) If not what is the new way of finding an instance ?
