> As discussed with [~tmueller] and [~teofili], it might be beneficial for query performance if it was possible to determine read-access without having to create the {{Tree}} (and thus the hierarchy). The latter (as present with {{TreePermission.canRead}}) is suited for regular repository read operations where the tree hierarchy is built anyway.
> since {{PermissionProvider.isGranted(String oakPath, String jcrActions)}} requires to resolve the path to properly deal with write operations, i would suggest to evaluate if adding {{PermissionProvider.canRead(@Nonnull String treePath, @Nullable String propertyName}} would give us some performance gain in the query case.
> initial (untested) draft attached for basic evaluation. proper unit and benchmark testing are required.
