There is probably a valid argument about the managing the logistics of poling places to be made here.

Jurisdictions need to know how many ballots, poll workers, and polling locations they need to actually run the election.

Registration also helps to determine what proportion of the electorate turned out. This can give hints to how well information about the time and place of elections was advertised and whether polling places were open long enough or at enough locations to give people the opertunity to vote.

The way in which registration is handled in a given jurisdiction can absolutely be designed to suppress votes.
