Add architecture.lullabot.com to Planet Drupal?

Would they be a useful contribution?

What is acceptable for Planet Drupal is listed on Content that is great for Planet Drupal → , while the content that is not acceptable is listed on Content that does not fit Planet Drupal → .

Yes, sorry I should have said I did read those docs. I just wasn't sure where to consider these. It's kind of "How-to" like?

I looked at the content listed on https://architecture.lullabot.com/adrs/drupal/.

To be how-to articles, each post should be complete by itself; they could be also split in two or three parts, if writing a single article would make it too long, but after reading the parts, but the readers should be able to know how to achieve something (programmatically creating a view, altering the response returned by a contributed module, etc) after reading the full article. This does not seem the case.

In none of those posts, Drupal is mentioned; reading them, it is not clear if what described is about Drupal or another CMS. They are useful considerations, but there is the context for those considerations is missing; with more background, those posts could make a good article (or a couple of articles).

Then, the posts have been created more than three months and three weeks ago. A feed with articles created by those posts would not appear on Planet Drupal, which discards articles after three months and three weeks. (If the articles are already older than three months and three weeks, they would not even be added to Planet Drupal, when the feed is added.)

Yep, fair enough. We've written a few articles about our ADRs, the ADRs themselves are intentionally not how-to's. Thanks for taking a look!
