As far as I can see the RPMs from older builds are kept in the CentOS 
repositories but the associated module metadata isn't.

For example, you can see both softhsm packages from the above builds in:

But the "modules" file currently pointed to by repomd.xml only contains 
metadata for build 265 (search for "stream: DL1"):

I don't think there's any other way for dnf to tell that an RPM is part 
of a module before downloading it, but currently each time a module 
build is published it appears to push the previous version out of the 
"modules" repository metadata.

This leads to the current behaviour where disabling a module only hides 
RPMs from the latest module build, and earlier versions "leak out" into 
transactions, eg:
   $ sudo dnf -y module disable go-toolset
   $ sudo dnf install golang
   (incorrectly offers to install package from previous module build)
