Ah, yikes. I guess we should sneak the show_mz into the IOContext instead.

Would you want this one done? — GeoInterface.jl throws a MethodError when displaying a FeatureCollection that wraps a bare-tuple geometry, because an unsupported show_mz keyword is passed down to the nested geometry's show call (#219). If yes, we'll do it and open a PR; if not, say so (or just ignore this) and we won't touch it.
How it works: an AI agent does the work against your write-up. Before anything reaches you, the change is rebuilt and tested from a clean copy of your project, using your own test suite, and the results are kept in a record you can check yourself. A human reviews it, submits it, and answers the review. You keep full control — nothing lands unless you merge it.
We're testing whether work offered this way is useful to maintainers — a blunt "no" is as helpful as a yes.
