I don't understand the point of the question. There's no rule against driver coaching in particular. The driver cannot be aided when he is driving. To my mind, strictly interpreted, that means you can't say anything at all to your driver during the race; all of the things teams say to drivers during racing are meant to be of assistance to the driver, otherwise the teams wouldn't say them.
I know I'm in the minority, but I can't see any real basis for being okay with some messages that aid the driver but being down on others. And there certainly isn't any basis for any such distinction in the regs. Personally I'm fine with whatever level of coaching a driver happens to find helpful. I don't think Jaques Villeneuve was a bad peddler, yet he used to have Jock Clear in his earhole literally telling him "go left" or "go right", like a Nascar spotter, on the first lap of races. But if anyone has a problem with teams talking to drivers and thinks it's covered by the regulation that says the drivers have to drive "unaided", then as far as I'm concerned those people should want all radio transmission from pit to car banned.
If I were a team boss I would quite possibly be willing to go to the ICA over this if necessary. What actually seems to have happened, as far as I can see, is the FIA started off threatening to ban pretty much everything except messages without which the drivers wouldn't be able to finish the race, and since then the teams have secured a specific exception to the "no coaching" rule for more or less everything they want to say to their drivers. I'm sure it's been agreed, formally or informally, that "this is good, keep doing this" is fine.
