Unless things have changed recently, and I've missed it, we don't know in what order the various edit tools are actually executed. AFAIK, this new "feature" (which has been in Classic for quite a while) is purely a convenience for the user so that they can group their most used tools to the top of the panel and keep the least used tools at the bottom, thus minimising travel between the various tools.
In terms of the Profile/Calibration tools, yes in the past the Calibration panel may well have been the first tool executed, but only because the profile was selected in that panel. Now that the profile is independent of the Calibration panel, it's logical that the profile is now the first item used, as that would be needed for the initial raw conversion.
