Is your feature request related to a problem? Please describe.
Some people have trouble building electrs (see e.g. #252) because of sysconf dependency, some may not need it and thus avoiding compilation time and potential attack surface may be preferred.
Describe the solution you'd like
Make prometheus optional using a Cargo feature (default on, I guess) and document it. Packagers are still encouraged to include it. Put all related code into a single module to cut it out cleanly and create an empty module with empty structs and no-op methods.
Describe alternatives you've considered
- Try to fix lib bugs - nice but it's still more moving parts than necessary for many people.
- Rewrite dependencies somehow to bypass C/OS APIs - difficult, I guess?
- Do not support niche platforms
