Right. Custom Rule properties are not collected for later use. Rule behavior is
parameterized via properties of the respective module/product.

Custom properties are collected and made accessible in rules for the Product,
Project and Modules items.
For all other items, only the built-in properties are retrieved and acted upon
according to their documented semantics.

Yes, I can see how that could be useful (see also the TODO item in
CppModule.qbs). You might want to create a task in our bugtracker.
