Right now I keep pollution quickwit/quickwit with my qw-fulmicoton-experiment tags.
In particular, it overrides the latest tag.

We should publish those under a different tag, using a different prefix scheme.

tagging as low priority

I think you meant different image, for instance quickwit/quickwit-dev:fulmicoton-123?
