The artillery has its own way of calling companies, similar to units that descended from cavalry in some countries A company of artillery is called "battery" (Batterie). It took decades to shed the traditional Abteilung (~detachment) and call a German artillery battalion a "Bataillon" instead. The (West) German artillery also needed two generations to finally incorporate WW2 lessons and admit that joint fire support teams (forward observers) should be versatile and call for artillery, mortar and close air support instead of the army having separate observers with different terminologies.
So there's ample evidence that a certain conservatism and tradition-orientation exists in the artillery, including the German artillery.
Technology and procedures challenge another tradition of the artillery, and this time it does to the very heart of it:
Artillery guns (or multiple rocket launchers) used to be sited together in groups of 4-6 heavy weapons. Battles saw grande batteries from the 18th century onward, ad hoc concentrations where dozens if not hundreds of guns were sited together.
This is an obsolete approach. Such artillery concentrations create high value target areas and attract counterfires. There's no need for such grouping of guns any more anyway; as it was mostly done for economy. You needed less of the expensive radios, less land navigation effort (especially north finding) and less fire control personnel and equipment if you did all this for a battery instead of for every single gun. Nowadays be have GPS/Galileo, inertial navigation systems, quality maps and radios are ubiquitous and relatively cheap.
Modern self-propelled guns are equipped with what they need to go into position to fire a mere minute or two after receiving a fire mission by radio. They can do so on their own, knowing where they are and which direction they're facing. They receive meteorological and fire mission data by radio and calculate their own fire solution by computer.
This finally begs the question: Why do we have batteries?

The tactical reason for batteries is gone. Whatever organisation the artillery should have should thus be based on administrative efficiency considerations. A modern SPG usually has a crew of 3-6 depending on type. A typical battery/company of six such guns would only have 18-36 (wo)men at the tip of the spear. That's rather a platoon. There's usually lots of overhead in such units beyond the SPG crews, but one could easily argue that an artillery battalion could or should look look this
HQ (with signallers)
Meteorological and sensors company*
Fires company** (including a small unit meant to scout future firing positions)
Munitions company*** (with 15 ton 8x8 lorries)
I suppose such a reform could be used as a positive proof for a readiness to adapt to modern times by an artillery branch.
*: "Sensors" should include artillery radar, acoustic triangulation sensors and tethered drones for muzzle flash triangulation. A good case could be laid out for having JFST and non-portable free-flying drones in a non-artillery unit directly under brigade HQ control, serving the HQ's, tanks', infantry's and artillery's thirst for information equally.
**:: SPG and MRL may be mixed. There's no reason to separate them any more. Even surface-to-air missiles could be employed by the company.
***: with PLS / MULTI /DROPS equipment. Meant to haul munitions from a corps logistics hub area and carry up to two days worth of munitions till needed. Then drop the pallet next to a SPG and return to the hub. A very different mode of operation from the other units..
