This behavior dates back to commit a20dd508aa38 ("simplified invocation
- added automatic IDE disk geometry guessing to reuse old disk images
directly", 2003-09-30), which is when "-append" was added.
In said commit, "kernel_cmdline" was *appended* to "params->commandline"
with pstrcat(). The rest is history.
TL;DR: "just because" :)
