Workflow choice for novice user

Let me summarize high level questions.

WORKFLOW

Is this right order of steps?

FOCUS

• basic workflow without git
• basic workflow with patch-unapplied git
• gbp/debsign/dput workflow with patch-unapplied git
• sbuild/dgit workflow with patch-applied+auto-commit

NON-FOCUS

• dgit-maint-debrebase exposure should be limited

GPG key

• Correct key usage is ~/.devscripts configuration issue (not debsign usage issue)
  • I used to worry to use my old RSA1024-key over Debian keyring registered one.
  • I am now worried not to use my newer Ed25519-key prematurely

My question is: Should we need to address this is README? Maybe main text is the right place.

salsa-ci

Q1: Which is the best generic template content?

---
include:
 - https://salsa.debian.org/salsa-ci-team/pipeline/raw/master/recipes/debian.yml`

or

---
include:
  - https://salsa.debian.org/salsa-ci-team/pipeline/raw/master/salsa-ci.yml
  - https://salsa.debian.org/salsa-ci-team/pipeline/raw/master/pipeline-jobs.yml

Q2: how to deal salsa-ci for (quasi-)native package like this debmake-doc without separate upstream?

Q3: What kind of exra comment to be added in template salsa-ci.yml generated by debmake?
