I think that's wrong.

Because if the output of the text template should be processed further (for example, it creates a .cpp file which should be compiled into an application or library), then the output artifacts need to have a corresponding tag set via the ` texttemplate.outputTag` property.
And if the texttemplate module would set `additionalProductTypes: [product.texttemplate.outputTag]` then the Product containing the template would also get these tags (for example "cpp") which is wrong (it's an application/library, not a cpp file).
