Discovery of game mechanics is also part of the game.
You’re obviously entitled to your opinion, but the developers aren’t obligated to agree, and it’s their system, so it’s implemented according to their desires.
The practical outcome of this discussion: don’t be surprised if this is not a bug and complaining about it here is useless. If it’s their intended design it literally cannot be a bug according to the only definition that matters: theirs.
You should hedge your bet by posting a suggestion to change it in a non-Support forum. (This is what you would do if you don’t agree with an intentional design choice.)
If you want to report this behavior as a bug, there’s already a thread open in the Bug Reports forum for this. (Reporting a gameplay issue in Technical Support won’t work, since this forum is restricted to troubleshooting computer and connectivity issues.)
If you wish you suggest the developers reconsider this design choice, I’d recommend a topic in the Quests forum. This one is already open.
