Allow charmcraft status anycharm for everyone

[taurus-forever]

What needs to get done

Hi,

At the moment charmcraft status anycharm can be executed by the charm maintainer/publisher/collaborator only.
All the rest are rejected:

> charmcraft status grafana-agent
Store operation failed:
- permission-required: No publisher or collaborator permission for the grafana-agent charm package

Why it needs to get done

Allowing read status access will avoid bugreports like this (wrong revision chosen as invisible on charmhub).

Can anonymous read access be allowed for charmcraft status?

Thank you!

Thanks for the request!

How would the information presented by an anonymous read with charmcraft status differ from what's provided currently by juju info? Currently, charmcraft status can provide information that only publishers or collaborators can access (e.g. it lists all active branches for a charm, which are not made available to the general public). The most straightforward way to do this would be to use the consumer API, but I don't think this would provide any information that's not already available through juju info.

Hi @lengau, thank you for the fast reply!

Yes, I agree juju info helps a bit here. However:

1. Usability: juju info grafana-agent paged per architecture. It is huge page output with the necessary information at the bottom:

2. Juju info doesn't show/expand all details about bases/series, compare track 1 for pgbouncer:

3. juju info ... --arch all is just useless:

09:58:03 ✔ taurus:~$ diff -u <(juju info grafana-agent) <(juju info grafana-agent --arch all)
09:58:05 ✔ taurus:~$ 

Users have to execute juju info --arch for each arch one by one (amd64|arm64|ppc64el|riscv64|s390x) to see the same data as charmcraft status.

4. (separate topic) juju info is showing 'release date' (nice!) but charmcraft status doesn't (sad :-( but separate UI topic...). And even more, charmcraft status shows date as a expiration date for charmhub branches (which confuses even experienced developers due to fundamental difference in snap info+juju info to charmcraft status):

This example shows the problem of jumping between tools with different UX.

Thank you for possible improvements here!

P.S. re: ... it lists all active branches for a charm, which are not made available to the general public...

Let charmcraft status show the public information only to non-authorized users? Effectively hide all charmhub branches from the output.
