Currently incomplete (documentation is only available on interfaces),
because TH cannot set documentation on overloaded record fields
("Ambiguous occurrence ‘destroy’").

GHC 9.2.1 also enables Template Haskell to attach Haddock documentation,
which can be used to attach documentation from the Wayland XML
specifications to their generated Haskell APIs.

Analog to how low-level messages are mapped.

Experimental way to enable early object id checks, might be removed once
the higher-level api generater can provide the checks.

I really like the idea of a pure wire protocol implementation and might
revisit that later, but to get an MVP it's much easier to use STM in the
core, since all interface impementations are going to use it anyway.
