Status message format

Maslow sends a status message every so often

[PE: .423, .454, 777, 1232.3, 4245.8]

It seems to me that it would be good to add “extra” into the 1st line (with tags), eg


So that webcontrol can check for yep, I have the word PWR, do something with it, or nope, no PWR; skip this section.

But… would that break other things? If “odd stuff” is in the status message, will it break something like CNC.js?
