Please move "Better Normalizers" into core

100% agree! This was introduced so profiles/modules could depend on these normalizers. I'd think of it as a staging ground for improvements on the way to core, much like "entity".

+1 to this. there is also this issue #2670954: Add Better Normalizers as a dependency to add this module as a dependency to default_content.

Updating the link to the latest REST priorities issue

Probably Drupal 8.6.13 have same normalizers as this module (no changes in file and menu link content export with default_content_deploy module). Please update the documentation and module page with versions interval when this module is needed.

I think it's still needed. When I export a file with better_normalizers enabled, I get a data key with the base64 encoded file data. Without this module, there is no file data in the export.

I use file_entity for that, and all my files are exported.

#2852860: REST: top priorities for Drupal 8.4.x is closed yet better_normalizers still exists. Should this be moved into the core queue? What is the process for moving module functionality into core?

in Drupal 10, default_content_deploy still needs this module to export files correctly
