Thank you for the comments!
Yes, having some sort of history would be ideal in this case.
However, I am not sure how to implement those features at this moment,
so I will take some time to consider.

At the same time, I think having this metrics exposed in the
pg_stat_all_tables comes in handy when tuning the
maintenance_work_mem/autovacuume_work_mem even though it shows the value
of only last vacuum/autovacuum.
