Does this version actually exist? I can only see 4.15.2 https://registry.bazel.build/modules/z3/4.15.2/overview

Also is there any way to avoid the git_override()? Won't all downstream users of rules_hdl have to start setting that manually

git_override(
module_name = "z3",
commit = "ac9156f97cb44e56472e1c841f7a2beb1e976b24",
remote = "https://github.com/Z3Prover/z3.git",
)

bazel_dep(name = "rules_7zip", version = "0.0.1")
git_override(
module_name = "rules_7zip",
