Is docker support for 32 bit arm architectures planned?

[Edited to focus on docker support for 32 bit arm. Before, it was asking for general 32 bit arm support]

Hi all,
this is my first contact with GitHub discussions, so please let me know if I need to adapt/change sth.

I am currently evaluating grafana-agent (flow mode) to collect metrics and logs. While it works great on my x64 machine in a dockerized setup, it does not seem to support older raspberry pi models. More precisely, I am talking about a raspberry pi 3 with the armv7l architecture.

I checked:

• the install docs: only 64 bit mentioned for arm
• docker hub: only 64 bit support for arm
• binaries in GitHub releases: only 64 bit support for arm
• the apt repo based installation method: grafana-agent exists but grafana-agent-flow does not
• for a corresponding issue in this repo: none found

The deb package contains a grafana-agent package that apparently can be started with AGENT_MODE=flow grafana-agent to use flow mode, so at least it seems to run on arm(hf). With some fiddling, I was able to use it to the full extent. But still, I am curious to hear whether docker support for this platform is planned?

Building it myself from the github repo failed because there was no matching agent-build-image. Building also this one locally failed because it relies on viceroy images, which again did not seem to exist for my architecture. Long story short, I stopped at this point. Before I invest more time here, I figured it might be reasonable to ask if arm 32 bit docker support is actually sth that is being worked on, or at least on the radar, or maybe not planned at all or even actively unsupported/discouraged to do? Maybe there is some piece of information that I overlooked, or someone from the dev team can shine some light on this?
