Yes, I'd be fine with that, as long as there are some qualifications for very young players and those with any physical handicaps.
Of course, this will only work for matches having referees, but in WNT events, all "last sixteen" matches have a dedicated referee. Automated break speed surveillance in matches not streamed or refereed sounds expensive.
Still, unless the penalties are stiff, it won't be enough to stamp out soft breaking. Perhaps a second break speed violation could be loss of rack and a thrid loss of match.
