I don't see how one is more difficult than the other, technically speaking. 
They're both just a bunch of assignments, though the .pri file seems to depend 
on some variables not defined in the file, but which can be easily inferred.

The two important details, though:
1) pkg-config is a standardised file format, the .pri isn't
2) the .pri file has the list of plugin types, to help static building and the 
*deployqt tools.

$ cat mkspecs/modules/qt_lib_network.pri lib/pkgconfig/Qt5Network.pc
QT.network.VERSION = 5.10.0
QT.network.name = QtNetwork
QT.network.module = Qt5Network.t
QT.network.libs = $$QT_MODULE_LIB_BASE
QT.network.includes = $$QT_MODULE_INCLUDE_BASE $$QT_MODULE_INCLUDE_BASE/
QtNetwork
QT.network.frameworks =
QT.network.bins = $$QT_MODULE_BIN_BASE
QT.network.plugin_types = bearer
QT.network.depends = core
QT.network.uses =
QT.network.module_config = v2
QT.network.DEFINES = QT_NETWORK_LIB
