This is an Open Source project with a single maintainer who is aided by volunteers.
The forum is generally speaking only for Hugo support or how something can work with/in Hugo.
I don’t quite understand the above questions.
Especially in relation to your question about converting Kramdown to Commonmark.
Hugo uses the third party/upstream Golmark Markdown processor, who in turn follows the Commonmark spec.
Anyway for reference please have a look at the:
Forum Guidelines as well the Requesting Help guidelines.
Thank you.
