Node edit form breaks for instance, because attributes in forms which are not cacheable are replaced with scripts from this module instead of the actual needed value.
big_pipe_nojs_placeholder_attribute_safe this is also noted as a style placeholder and therefor the assets are processed.
Diving into it even deeper shows that currently even if for a attachment response (which are multiple responses with big pipe) no libraries are blocked in this specific response. There is still processing done, because one of the responses does have something blocked.
Setup big pipe and cookie content blocker, edit a node.
Make sure that there are even libraries (css or js) in the response that might need blocking. Because in this case with big_pipe_nojs_placeholder_attribute_safe no js or css libraries are attached in the response.
This is also a performance gain.

This patch works well on 2.3.0 version. I updated the patch for the new module version.
