The problem with ResourceHandler is it doesn't easily support more complex scenarios. A few examples: security on resources, URLs that must find a resource path from the database, conditional resources (deliver resource A if the IP is x.x.x.x and resource B otherwise), etc.

Offering a more granular control to allow delivery of individual resources without the need of a ResourceHandler will drastically improve the flexibility of Undertow.

I would be ok with that, however why can't you just use the
ResourceHandler? PathResourceManager will use transferFrom if the file
is larger than a configured minimum (the transferMinSize parameter in
the constructor).
