No one wants to show up at the next war prepared for the wrong war. The mistake can be catastrophic. The Great Powers marched confidently into battle in

Hubin imagines small units moving around the battlespace passing from the control of different commanders....
Unimpressed, this level of thinking appears narrow, on the order of "don't need fronts now with turrets on tanks, since they can shoot backwards" level of depth.
The novel situation with regard to land warfare (fire on the move, long range precision strike...) is very old in naval and aerial domains. Then there is horse archers if you push it.
The concept for front and rear is defined by information more than tactics: whether you have information or not.
Precision long range fires do not facilitate dispersion, massed long range fire does. When the attack is limited by sensors, dispersion is useful (but not universally so, extremely concentrated forces can avoid recon for outsized effects if coverage rather than signature is limiting factor). If attack is limited is limited by active defensive measures (interception, soft kill), "concentration" of mutual support is the solution.
The idea that forward forces exists to find the enemy is all about exploiting enemies on old paradigms and not about facing opponents with doctrine and equipment matching modern technology. An non-stupid enemy can read RMA (now 40 years old!) and understand that long range precision strikes is a thing and there is no reason to leave forces around to be pounded without reason. For forces in contact, a few characteristics would be needed:
1. Speed to avoid long range fire
2. Stealth and sensing power to detect and respond (either evasion or destruction) opponent sensors before detection
3. Low cost to sustain attrition via long range fire
4. Required in achieving nonlinear (decisive) effects outside of attrition
Against a enemy that follow those concepts, the front force would be fighting a counter ISR battle with similar opponents, the loser would lose information and risk effective targeting to the rear. One can also see how powerful air superiority is in this regime and air-ground cooperation is decisive.
The notion that long range precision strike means end to concentration is funny, when one could cram 1 million loitering munitions and 1000 loyal wingmans in a singularity in space and time. Just because concentration is difficult in one domain does not mean it is impossible in other, interrelated ones: machineguns already made "mass impossible" but offensives still happened, even without tanks! Artillery can be massed to generate local superiority.
The notion of complete battlefield information is also meh. Now imagine two sides with total information: the outcome is overdetermined and there is no battle between semi-rational actors. War happens because of incomplete information. In any case, it is short range weapons relative to sensors that result in good information: long range fires merely closes the equation and the ability to kill sensors at ranges returns uncertainty to war. The obsession with old "maneuver" platforms with miserable signature to, weapon and sensor range ratio is what makes this ideas a thing: they won't be the arm fighting the counter-ISR battle.
Can't comment much on command relations, not having taken a leadership role, but if it is the same quality of thinking I'd probably discount it.
