When did sub-tactic become visible to opponent?

As per title, up to certain point opponent could see only your main tactic (offensive) when checking opponent information in gameplan, even if you had the sub-tactic (defensive) active. Today I matched with a streamer and later when I watched the game, I discovered that indeed my sub-tactic was visible on opponent information in his gameplan during half-time. So when did this change?

Probably those who abuse the out of position main tactics are the reason for this. But it ruins the inception of a smart tactical decoy for the rest of us.

What are your thoughts? Personally I think if it were to be somewhat realistic to actual football, no opponent tactics should be shown at all, just their starting/current eleven at any point. A real coach adapts to what they see on field. But since it's a videogame and many are not that football nerds I get the need of having it open. At least though switching from main to sub-tactic notification (and even the attack/defense bar) should not be visible to opponent. So that element of switching tactics ingame can be actual factor.
