If there was such a directory, yeah, it could be. But there's no such
directory. It's up to the hotplug script to decide where to look for
the firmware bits it's going to give back to the kernel. It can be a
directory, a collection of directories, a tarball, a database, anything.
So the kernel can't look it up.
And then, if the kernel could look it up, it might as well get the data
straight from the filesystem. The reason is doesn't is precisely to
enable userland to control not only where, but also how firmware is
stored.

It would, if the kernel could tell how userland would resolve filename
requests. It can't. That's why my proposal involves userland to tell
the kernel what pieces of firmware are available upfront.
