Hi @oleg-nenashev , thank you so much for the review on the proposal! Just a small query, you mentioned "Note that tracing fingerprints between instances might be a good use-case for the future (sharing artifacts, tracing Docker images across a wider setup, etc.)".
Tracing fingerprints is a part (goal) of the External Fingerprint Storage API Plugin that I have planned. So tracing is happening, just that I am isolating this functionality into the plugin, to not suddenly change the design of the current offering.
However, if you would like to have this design ingrained, i am mentioning an alternate approach in the appendix, but then that would take away the need for the External Fingerprint Storage API Plugin.
