Can we prevent cell coordinates from being created? It's a memory waste in the best case.

What if you delete the `dm_sparse_localize`? I hate using options for correctness of code anyway, but we shouldn't need it.

Right, that describes what happens for Matt-style periodicity, while isoperiodicity should not require any cell coordinates. This is quite dated now, but it was working when I created it, and...

I think in both cases we can use isoperiodic, and perhaps assert that it is not topological-periodic. @knepley This is in `DMLocalizeCoordinates`. Can we use `plex->periodic.face_sf` or something so we...

I don't understand this issue. We can now read the output files regardless of which ints are used, or we can do tests that don't have reference output.

In my PETSc MR? It just works. You can write from either `i32` or `i64` and read from either. We don't have to change data files or code.

I'm fine with providing this key, though it may be tricky to record the right one. For example, when PETSc `--download-libceed`, it sets `CFLAGS` directly, not via the `OPT` convenience...

I think it'll be an issue if allocation is needed. We should eventually expose a pre-allocated tape as can be done using C-Enzyme.

I would note that even if the LLM is exclusively trained on MIT-licensed projects (which is true of none of the commercial services), creating a derivative work without attribution is...

Suppose a human [types](https://devclass.com/2022/10/17/github-copilot-under-fire-as-dev-claims-it-emits-large-chunks-of-my-copyrighted-code/) `// sparse matrix transpose`, presses tab, and gets a page of code that still has namespaces from an existing library with copyright/attribution stripped. What does it...
