“The audacity of the wheeled cannon is the maximum efficiency,” Beaudouin told Defense News. “You sacrifice nothing in terms of firepower, rate of fire, precision and range, and you’ve got a truck, armored all the same, but which is able to be nimble, which is very stealthy.”

Beaudouin was part of the French Army’s decision to buy an upgraded Caesar, so he might be suspected of bias toward wheels. But at least nine other countries, including the U.K. and Germany, decided to invest in self-propelled wheeled howitzers in the past year. Analysts said the Ukrainian experience is driving military planners’ interest.

...

Interest in wheeled self-propelled artillery flows from a desire for a “much higher degree of mobility and survivability” than towed guns, said Daniels. Military staff who see wheels as an attractive option over tracks “often define survivability in a broader way, as opposed to seeing it purely from the physical protection offered by onboard armor,” he added.

“Ukrainian use of shoot-and-scoot artillery fire suggests that the future lies in highly mobile artillery, be they tracked or wheeled,” Jones said.

I think the unwillingness to switch Ukraine to 155mm caliber prior to 2022 has less to do with the west trying to not provoke russia and more with Ukraine's desire to use existing stocks and tooling in domestic ammo factories. They themselves ordered DANA M2 in 152mm caliber in 2020. Only after the invasion they realized they will need much more ammo then they can produce domestically and west started providing 155mm systems. Already in 2022 Ukraine has been given German PzH 2000, Slovak Zuzana 2, French Caesar and eventually Swedish Archer. The ammo problem simply took time to solve, but it seems European productions is ramping up and the Czech initiative is still ongoing.

The need for armoured cabin is now well understood and I would say that Swedish and Czech solutions go even further with autoloaders and targeting computers reducing the crew needed to as little as 2 and removing the need for the crew to leave the cabin during a fire mission.
