Someone who asked me for advice uses zref to have multiple paragraphs written to the aux file for a single referencing label.
Since the zref macros are not defined in terms of \long, she uses a copy of \par that has a different name to create new paragraphs.
I am not really thrilled with this approach
Now, of course, the following problem has arisen:
Such a collection of paragraphs consists of many characters, which are written to a single line in the aux file.
This makes the aux file look unorganized.
