I've considerable experience in screen building and a bit using remap. I've fairly often came to the problem of needing information from the remap (or linuxcnc proper) presented to the screen. By design linuxcnc has status messages that are usually used for this but it is difficult to extend. On a recent fanuc style lathe tool remap, I wanted the wear offset number displayed on the screen. Parameters work well for passing information internally, accessible in gcode and can be stored at shutdown. But they are not accessible in screen user code. I got around this by building a HAL component in the remap to copy a parameter to a HAL pin. HAL is accessible everywhere and is easily extendable.
Then it occurred to me - why couldn't all parameter data be held in a HAL comp? Can anyone else think of a reason it couldn't or shouldn't ?
