From
https://www.yoctoproject.org/docs/latest/bitbake-user-manual/bitbake-user-manual.html#gitsm-fetcher:

"The Git Submodules fetcher is not a complete fetcher implementation.
The fetcher has known issues where it does not use the normal source
mirroring infrastructure properly. [...]"

For that reason already, I would strongly discourage the use of this
fetcher. And that's why it was never tested with Isar (to my best
knowledge).

In general, git submodules are hairy. And specifically in the context of
distro (like Debian), their presence indicate that you rather want them
as "Build-Depends" and properly packaged.
