It isn't a common spaceframe. While the regulations about rollcage / chassis construction are quite prescriptive, each team has designed, and either manufactures or outsources, its own chassis.

They are so similar in size because it is the sweetspot in regards of what is possible. I'd guess you couldn't really go any smaller due to packaging constraints and would potentially end up with a too short wheelbase if you'd were to go any smaller. Equally you wouldn't want a bigger car for obvious reasons, but you want to maximise the wheelbase (think a wheel in each corner). If we look back through the years we can see that manufacturers tried to go for a car that is round about four meters long whenever the regulations allowed.
Also as allready mentioned it is not a spec chassis, we are thankfully still talking about three different cars, not three different silhouettes.

The real pity is that spaceframe chassis was really only brought in so new manufacturers could enter and re-size their relevant car model to fit.
And after doing so, there's been no new manufacturers come in anyway....

There's more to it, making the cars lighter and better fitted for the hybrid unit, and also allowing the common safety cell to be used, increasing the safety of the cars.
The current three year regulation cycle cannot attract new manufacturers right now, no one will join in just for two years, unless FIA extends the current regulations somehow (maybe with everyone's own hybrid unit or something). Another thing is that these space frames could also be used for electric rally cars, if that's what the main class is in 2025, but too early to make guesses.
And finally we must remember that keeping the current manufacturers was every bit as important as getting new ones.

Wiki
"Tubular space frame structures are permitted allowing for scaling of production models."

Yes. It is now allowed to do scaling.
A nice analysis from the rally: https://dirtfish.com/rally/wrc/what-we-learned-from-rally-italy-sardinia-2024/
