[policy, no patch] Backport policy for Starterkit theme changes

The allowed changes for minor releases → does list CSS, markup, or template changes (except for stable base themes) for minor releases. However, the allowed changes for patch releases → states that "non-disruptive bug fixes" are allowed. So, the fixes described in the issue summary would fit within the existing criteria.

An extra sentence could be added to explain that changes to Starterkit are not disruptive. However, Disruptive → is defined later in the document and can be evaluated in any issue or amongst the core committers. Also, there is always tension in such documents to provide both detail and flexibility in interpretation. I would rather leave the policy as is.

I think the policy works as is. Know it comes up often about wanting to make twig changes on themes and usually we can re-work that solution to not include twig tweaks.

Maybe worth exploring deprecation solutions within twig? Like

If on 10.3 this is the old that will break in the future, use 11.x way.

idk if that makes any sense but marking RTBC that think leaving it is fine.

This needs a proposed wording and link to the policy being changed.

As stated in #4, I don't think any change to any existing policy is needed. I will try to make it clearer.

The backport policy → states

Most patches that are allowed in patch releases can be cherry-picked between minor versions. Committer apply these patches to both branches at the same time.

The allowed changes policy → lists what can be applied in patch fixed and that includes

non-disruptive bug fixes

. Since, the changes to Starterkit theme CSS, markup, and templates are non-disruptive, they are already covered. Therefore, there is no need to update policy.

Restoring RTBC since I've only added more explanation and updated the IS.

Ahh sorry, that makes sense! Moving this to fixed then.

No worries. Glad this is resolved.

Automatically closed - issue fixed for 2 weeks with no activity.

Changing to latest version when this was closed.
