I second this. My current (not-ideal) fix is using embedded notes. Example:
file: jogging.md
Current_Streak:: 20 (last updated: [[2022.01.21]])
Longest_Streak:: 42 (last updated: [[2021.07.03]])
^093df1
file: health-tracker.md
![[jogging.md#^093df1]]
It’s not great, and has to be manually maintained, but it’s simple and works.
Ideally, the plugin would allow for quick and easy +1 of a streak. I bet something can be put together with MetaEdit. I’ve been meaning to tinker, but have yet to do so.
