Thanks for your report! I'm sorry that the current implementation causes this problem, and we know that this binds more resources than it should. The changeset size is a known issue that is fixed with the next version of Wheelmap that is currently in beta.

See https://github.com/sozialhelden/wheelmap-frontend/issues/327 for updates on this. You can try the new version on https://beta.wheelmap.org if you want to check the new behavior yourself.

This changeset is 12 years old :) related, though: https://github.com/sozialhelden/wheelmap-frontend/issues/329#issuecomment-1032912659
