That's simply not true, at least not for Debian. If you actually use the 
distro tools [1] the only assumptions are made at kernel *installation* 
time, not at kernel build time.

I've been using initramfs-tools generated initrds for years without 
problems, and that includes "root on LVM on LUKS encrypted partition" 
and "root on LVM on RAID" setups.

Cheers,

[1] I.e. if you build and install the kernel as a .deb package using e.g. 
the deb-pkg target or kernel-package.
