This will make it more difficult to backport changes across this line in the code but I still like the change

[MattKear]

What is the advantage of going to the macro for GCS_SEND_TEXT? I am not challenging the change, just want to understand the advantage 🙂

[rmackay9]

@MattKear,

The only advantage that I'm aware of is that the call disappears on AP_Periph. I like the consistency though even for those libraries that will never be included in AP_Periph
