My suggestion applies as well to modules as anything else.
What "like Module.symvers" means is something like:
name1 vmlinux %s
name2 fs/nfs/nfs %d
All the modules built by the same kernel build go into this one file.
Modules packaged separately for the same kernel could provide additional
files of the same kind.

That's clearly straightforward to do given the basic markers data structures.
It does not address the need for an offline list of markers available in a
particular kernel build or set of modules that you are not running right now.
The approach now available for that is grovelling through the markers data
structures extracted from vmlinux and .ko ELF files offline. That is more
work than one should have to do, and has lots of problems with coping with
different packaging details, etc.
Thanks,
