Yep, I'll try to do it soon.

I have a blog post task in my backlog, I want to upstream more home
services before publishing the post.  It's not a blocker, but a nice
thing to have.  There is another ongoing work, which I would like to
finish before making a post.

Another option is to publish this post some time after 1.4.0 release, so
everything I want will be finished to that moment.  I don't see reasons
to hurry, so it's a viable alternative too.

I burnt out a little during upstreaming process, it was quite slow and
painful at the beginning and increased maintanance burden of rde for me.
A little too early merge + uncoordinated changes of basic primitives and
service configurations also hit me quite hard and forced to spend some
time bringing rde back to working state without going a step further.

I took a break and after that started to cleanup small Guix Home issues,
develop/improve home services in rde repo and finally started to work on
new rde features.  Still feel a little burnt out and I try not to do

Now to more technical details:

When I started to work on Guix Home I explored different system services
configurations and tried to extract some common patterns, it was
relatively hard, cause of implementation inconsistencies.  I wrote
notes, extracted most common patterns and come with some approach for
writing service configurations.  During development of Guix Home it was
slightly changed, but most of the home service implementations are

gexp -> file-like change done in Guix repo for shell service
configurations and text-config type partially breaks the ideas I have
about how services should be implemented.

To continue upstreaming home services from rde to Guix I would like and
actually need to have an established style guide on how to write service
configurations to make sure service implementations are consistent.  I
started to write a manual section, which we can collectively review,
discuss and adjust it to get such a style guide.  Cause of burn out and
a lot of unrewarding monkey work I've done recently it's a little hard
to focus on this task, but I'll try to send first drafts to mailing list

So there is some work happening, but maybe not so visible.

Sorry for being not very active on ML recently, hope after core-updates
merged now you have a little more free time, so we can faster reach the
agreement on service implementation style guide and more people will be
able to contribute high quality services for both Guix System and Guix
