Description
It'd be nice if ResourceAssembler toResource[s] method allowed a Map<String,?> to be passed in with the entity to support more complex link creation. This would allow for creating links nicely with linkTo(Class controller, Map parameters). E.g.
D toResource(T entity, Map<String,?> params)
Without it, it seems we either need to create an instance of the ResourceAssembler each time so that we can get the params in or post process (e.g. with a ResourceProcessor). I'm happy to submit a pull request if this is something of interest?
On a side note... is there a mailing list where such things are discussed beforehand? and... thanks for Spring HATEOAS!

Research direction
Start by locating ResourceAssembler's toResource and toResources methods, then inspect how linkTo(Class controller, Map parameters) is used. Check existing assembler tests before adding coverage for passing parameters with an entity; done means the parameterized overload works without requiring a new assembler instance or post-processing.
