I would think that it is intentional, so that different managers from the same league can't "cooperate" when scouting the draftees. As the numbering of the players is randomized for all managers, creating a similar system with the draftees having characteristic features such as names is probably not that easy. Maybe it could be implemented, when a draftee has been at least "scouted" and "interviewed", so a manager has spent at least 3 scouting points on them?
Similar question would be with the revelation of nationalities for the Utopia draftees during the scouting phase. 
Yeah, I get that...however, are there enough managers who would actually use that team-approach to make that a genuine reason not to include names? I don't know.
Mind you, it's also nice to get the names when the draftees arrive in the team too.
Just thinking out loud.
@ regarding the Nationalities...surely that is something that can be done without too much of a problem.

Home Grown; for teams who like a challenge!
