A couple of reasons...
a) Bugs happen. Sometimes bugs are latent, and we later find ourselves
in an unenviable position of not being able to work around a problem
unless we know that we were loaded by <loader X> with <problem Y>.
b) Distro installers or other distro components sometimes find this
useful.
