I'm closing this PR. The pytest plugin lacks unit tests. I think it makes sense to first consider adding tests for the plugin to verify changes (like those in this...

converted to draft until https://github.com/asdf-format/asdf/pull/1733#discussion_r1555834679 is addressed

The following branch of `roman_datamodels` adds `lazy` to the node converters (and makes some minor node changes to account for `AsdfDictNode` not passing `isinstance(..., dict)` etc) to allow lazy loading...

JWST regtests: https://plwishmaster.stsci.edu:8081/job/RT/job/JWST-Developers-Pull-Requests/1571/ passed with 2 unrelated (and common random) failures romancal regtests: https://github.com/spacetelescope/RegressionTests/actions/runs/9746576095 (I ran the romancal tests with `photutils==1.12.0` since 1.13.0 is currently breaking main: https://github.com/spacetelescope/romancal/pull/1291) ran with...

Related to this, a callback that modifies a non-dict/non-list node modifies the input. ```python import asdf class Foo: pass tree = {'f': Foo()} assert not hasattr(tree['f'], 'bar') def callback(obj): if...

Runs of romancal and jwst regtestsshow no`AsdfDeprecationWarnings` indicating so neither of these packages serialize a`named_tuple`.
