well, this can be implemented as a configurable option, so users can
decide by themselves if this is a privacy violation or not (unless
explicity forbidden by law).
In the other hand i think it's not very good that maintainers decide
what's philosophically right or wrong appart from strictly technical
questions, and decide by themselves what technology is right to use or not.
