It could be added on the website as a new line on the beatmap page, or as a counter in game somewhere.
I think it could be a nice quality of life update for us who like to know that kind of things.
If x beatmap isn't one of your 15 most played beatmaps, you have no way to tell how many times you've touched it.
#userlog exists, but it only gives you recent information like how many times you've played today or how many times you've retried this map in a row.
Since these counters already exist I doubt it would be much trouble to implement this feature.

no need to waste stars or bump anymore
