If the ITF is enforcing this rule and livescoring is to happen, then all ITF events must work with electronic scorecards so that they automatically transfer the data to the ITF site and/or the provider (e.g. betting site company that hires the service). Problem is ITF futures don't require chair umpires during the whole 8-day experience, and there are robin umpires in the first stages meaning one person controlling various courts (e.g. in Qualies).
It might just remain the way it is now. If a company wants the scores they have to have a guy courtside.
But yes, your suggestion would make a lot more sense, economically from Sportradar's perspective
