What should be the advantage of this change? If I want to switch the Julia version, I can just use juliaup default 1.11 or whatever, which then also works if I want to start julia without sysimage using julia --version.

Main advantage: creating two system images for two different julia versions at the same time. In addition it is more convenient to write.

[1-Bart-1]

julaup default 1.10 sets julia to version 1.10 on the whole system, and I am working on multiple branches at the same time: when building a system image and xz file I want to continue working on a different branch.

Not planned.
