Is awkward main still compatible with the last awkward-cpp, so that I can install this simply without recompiling?

I was also going to comment "wow, so many lines", but I see it's all tests for the different classes.

I think so. I'm testing against main here: https://github.com/scikit-hep/awkward/actions/runs/10163112284

And testing against pivarski/requesting_form_should_not_touch_shape here: https://github.com/scikit-hep/awkward/actions/runs/10163115961

Oh, apparently not. Let me see if I can get a new awkward-cpp into PyPI today.

[jpivarski]

A new version of awkward-cpp is available. You can just pip-install it.

[martindurant]

This seems to work as intended.
I still don't know how to solve the concat case, though - we can talk about that separately.

I like this! It makes sense that we don't need any shape-content information to know that the inner_shape is () -- the dimension is a form-level thing.
