Thanks for the explanation. I also verified that the package dependencies worked correctly. My updated package now depends on libcurl4 instead of libcurl5, so the new package was correctly installed. In my case I'll avoid doing any specific patch to keep the SONAME version the same if firmware upgrade works as expected.
