You don't understand. If you want this, than make sure that this "in theory it should work" really works, and then submit it to FPC. Open source works through own responsibility.

So e.g.
- verify which fpc targets use zip as distribution method. (can be done from makefile)
- verify that the zip unpackers used (including several built-ins) can actually decompress the p7ziped zips. Maybe not all methods are supported. (I'm sure that one had problems with stream zipped ones).
- verify that p7zip works in the build process of said releases, including possible difficult scenario's (network, lfn on all windows and several dos versions) are tested, with the appropriate fixes to the buildsystem etc.

You can submit the patches to the buildsystems (and the chose builds for the relevant platforms) to the bugtracker.
