GraphicsMagick supports decoding and retreiving many EXIF values (see
documentation for -format in the gm utility documentation), but
only supports updating one or two parameters (e.g. orientation).
As long as libexif supports decoding and encoding EXIF blobs then it
may be a good way to go. The EXIF blob ('profile') can then be
replaced.

The documentation is not necessarily poor. It is not replicated again
at every interface appearance. The gm utility documentation can help
quite a lot with understanding the C, C++, Perl, Tcl, etc.,
interfaces.
This project is staffed entirely by unpaid part time volunteers. The
project can be improved by submissions from additional volunteers.
