Speed boost pokemon are often banned, not just from OU, but from lower tiers, so they end up in one of the BL's.
https://www.smogon.com/dex/xy/abilities/speed-boost/In fact it appears that over the course of the past 15 years, every evolution line that gets speed boost has been banned from a tier at least once.
getting banned from a lower tier is not the same thing as getting banned from OU, of course, since the power level of each tier is different, but it does show that across the generations, across tiers, speed boost has been a consistently "broken" ability.
I've never really played lower tiers myself but I found this trend interesting nonetheless.
