Hi Ben,

sorry for the late reply. First let me summarize what we are going to accomplish in the near future and then I will go into

details on each of your points.

We are aware that the release of Modularity in Fedora was rough and we are working to fix that. What we are trying to

do now is to use what we learned in Fedora and RHEL and make adjustments/features/fixes in the codebase so Modularity

would be more user friendly and simpler.  It is a complex task which needs a lot of time and effort. 

Now to address your points.

With regards to MBS, we are in touch with the EXD team which is supporting MBS in Red Hat. Currently Mike McLean

and Kevin Fenzi are working on the deployment in Fedora infra. EXD people will announce MBS support on Fedora

devel-list soon. 

For Fedora 34, we have recently planned fixes which will help Fedora as well as RHEL. There is a critical issue with the

upgrade path of the modules. This concerns both Fedora and RHEL. The fix for this is the introduction of static contexts

and phasing out of modules stream expansion. As you said, we can only provide you rough estimates for Fedora 35. We

want to revisit the implementation of the default streams as this seems a feature created controversy inside the community.

We would like  to make it more straightforward for the consumer and the packager.

With regards to the deeper architectural changes, we want to get to the drawing board with Modularity. We already started

with the upgrade path fix and continue with default streams with respect to feedback and experience. 

In the long run, the success criteria would be that we phase out module stream expansion from Fedora 34 and revise default

module streams so we can use modular RPMs in non-modular repositories in Fedora 35.

We need more resources to work on long term tasks. Due to the COVID-19 situation, we do not know when we could extend

the Red Hat team assigned on the Modularity project. Anyway, if there are volunteers from the community who would like to

contribute, they will be welcome to join the project.  

We would also like to improve the communication with the Fedora community. Any help and feedback from the community

is really appreciated.
