We need to create tables to generate the voter list for the BoT 2025 vote. Once the patch is merged we will run the script closer to the vote itself (just in case additional wikis are created). See the similar task, for example, T368569.
I understand this is discouraged behaviour now (see T355594: For global elections, stop creating eligible voters table for each election on every wiki and keeping them forever) but I'm not sure if we have the time to experiment with new solutions ahead of this particular vote.
