Only works for some archivers / archive types. IIRC, LFS uses a self-extracting 7-zip archive due to the LZMA compression being better than most others for some file types. This also has limited features of what can be done when the unpacking process happens. Zip / RAR however, can be pretty much customised to whatever you want.. but possibly at the cost of some bytes in filesize.
Out of all the installer programs I've used over the years, from my own concoction using C++ and a zip library to InstallShield, the one I've always settled on is
InnoSetup. Free for both commercial and personal usage and although not as feature packed as InstallShield, _definitely_ much lighter and still very powerful (not that an installer for LFS requires complex procedures, I've already built one with InnoSetup in about 20 mins)
Whether it's warranted, or "the people" / devs want an installer available however is a different kettle of fish
