The record tag currently has 127 questions, and this makes all the valuable answers about space records (most, smallest, etc.) easily accessible to future readers.
We also have classes of questions "What was the first (or earliest)...?" and "...last...?" as well as "How many...?" questions.
I wonder if they should be either added to the record tag1 or to a new tag that serves to help group these answers? First (earliest) and last are sort-of like records, though they can't be broken. (However they can be corrected). Some "How many...?" questions can have permanent answers, but for other's things may continue to change over time.
There are plenty of all of those kinds of questions so in this case adding lists of them does not seem helpful.
1as I have done (as an experiment) on How many bubble levels have been used in space? Were any of them used some place besides the Moon?
