G73 is peck-drilling in LinuxCNC
linuxcnc.org/docs/devel/html/gcode/g-code.html#gcode:g73

What makes you think that it should be something else?

The Wikipedia page lists FANUC G-codes, whereas LinuxCNC uses the RS274NGC standard from NIST.
You will see that even Wikipedia has G73 also as a peck-drill cycle.
But then, the RS274 document above lists G20 and G21 to change units in mill mode, and G70 and G71 to change units in turning mode.

Basically there are only 99 G-codes to be had, and different manufacturers add their extras wherever they can find a space.

G71 and G72 are a work-in-progress. The currently-available remap you might have found was written only to test an algorithm.

Here is the current progress in adding G71 and G72 "properly"
