Details

Currently the PKGBUILDs put .conf files in /usr/lib/modules-load.d to make the vbox out-of-tree modules load at boot. As the three modules didn't make it into the Linux kernel project, loading them by default seems quite suspect from system integrity and security perspectives. Because loading random kernel modules seems like it could crash my system or make it more pwnable, these don't seem like sane defaults.
This task depends upon

Another reason to not load the vbox modules by default is that loading out-of-tree modules taints the kernel (see dmesg). This means that when a kernel bug (unrelated to vbox) manifests, extra work (prevent the vbox modules from loading and reboot) is necessary to debug.

See https://www.kernel.org/doc/html/latest/admin-guide/tainted-kernels.html

> bug reports from tainted kernels will often be ignored by developers, hence try to reproduce problems with an untainted kernel
