I like to reopen this issue, and like to see if we can log these exceptions (warn or error).
Reason for this is that you have common use-cases where you are 100% sure if the resource exist.

> Following code: 
> {code}
> <sly data-sly-use.x="${ 'x/y/z' }"/>
> {code}
> You get now the following exception:
> {code}
> org.apache.sling.scripting.sightly.SightlyException: No use provider could resolve identifier x/y/z
> {code}
> In practice you want to have a null-value assigned to x, now developers will make a lot of checks to make sure the resource does exist.
> In addition we can log warning message when this happens.
