We are also facing the same issue in the project. I tried #2 patch and it is working fine for 1-to-1 mapping. Eg, Content type field is referenced with one paragraph type then it is working fine.
But let's say the Content-type field is referenced to paragraph type A.
Now Paragraph type A also has a referenced field that has multiple paragraph types B, C, and D.
Paragraph types C and D are not translatable still it will be part of the translation file.
