Hello,
That is a bogus comparison.
For the whole time I have been using Debian it has been accepted and
supported practice to _not_ use kernel-package but "make install" for
the kernel. Installing kernel's as .deb has always been optional.
On a freshly installed Debian system you can happily uninstall any
kernel-image package because there are no[1] dependencies on it,
*because* installing kernels with make install is supported practice.
OTOH anybody installing glibc with make-install will get "You shot
yourself" on _any_ report of a problem.

Package dependencies are simply not suited for depending on kernel
features, because
a) "make install" in sanctioned for kernels
b) The fact that a kernel-image is installed does not tell you
anything about whether the kernel-feature is actually available as
this kernel-image might be installed but not running.
A debconf warning displayed conditionally in preinst and config
(debconf will only show it once but depending on whether
dpkg-preconfigure is used one or the other script will run earlier)
still seems to be the best way.

specific kernel compiled with specific options selected.
