No, quite the opposite... deafening silence. However, 12 years ago the
module infrastructure looked very different than it does today, with
large chunks implemented in user space. These days the module
infrastructure is almost entirely in the kernel, which should make it a
lot easier to implement.
I thus suspect that it was just too hard when it was first proposed, and
then got forgotten about.
