You've completely missed the point of what I was saying. What I said was not that that error came up, I was saying that it is an example of a hot key that presents an immediate, clearly visible response when processed. As you said, it brings up an error message when you're not allowed to mount your chocobo. You're clearly not allowed to mount your chocobo while in the crafting position. What I also said was that the game did not respond in any way, not to the use of a hot key nor a macro (which would have also given an immediate clearly visible response). Thus, hot keys and macros are not being processed while in the crafting position. If they were, an error message would have been presented as it was processed.
Again, you're focusing on one example error message. The macro you may recall was an invite macro. You can manually type in the command to invite someone while in crafting stance, yet you cannot use a macro to invite someone. Passive or active mode does not come into this, the processing of input does. Whether it let me ride the chocobo or told me to try again later, whether it let me invite my mule or told me he was already in my party, it's all the same, it's all processing the information being input. No feedback whatsoever from things that normally do give feedback indicate a simple block on processing those sorts of input in that sort of (crafting) situation.
I don't know how they're going to handle it either because obviously it isn't in effect yet, but it is quite clear that they will have to allow macros and hot keys to be processed while in crafting mode. This is likely something built into the foundation of the interface, and such fixes have been put off till 2.0 for even the seemingly simplest of things so I will expect the same for this. If they surprise us then great, if not, we'll have to wait for 2.0 as with many other things.
Saying something doesn't help truly doesn't help. Saying what does help does help though. People have not just been saying "Poopoo to SE! You stuffed up! Go and find a way to make us happy!" People have been saying things that will help with basic functionality of the game, giving constructive criticism, something that does guide the way the game is designed to a point, while not asking for anything that would disrupt the play of anyone but would help the many crafters and gatherers out there a great deal.
Time will tell, as you say. We will see what comes of it. What I said about the current mechanics still blocking its usefulness when in crafting mode still stands until they fix that aspect though. There is no way around that. It's like telling people they can type all they want and then taking the keyboard away for a few hours, without input they cannot do anything, and blocking input blocks this update for a great many of us.
