It's very much in the spirit of MSH's DBs. The closest thing I've seen is Icehockey360.ru's measurements comparing boot and holder dimensions for the sizes he was trying: https://icehockey360.ru/baza-znanij/geometricheskie-parametry-stakanov/
It's on the older side now, and there were some surprises in there which makes me wonder about his methods. The general trend that emerges already in his measurements is that the industry was trending toward standardization. I think that process is now complete. True's new holder is supposed to be more in line with Bauer and CCM and I vaguely recall Warrior's skate representative saying on HockeyTutorial that their holder has the same pitch as the others. If those observations aren't mistaken, most of the value in the holder db would be to archive historical idiosyncrasies which have gone the way of the cookie cutter in recent years.
