Do we still need both Address Suggestion & Address Autocomplete?

I'm also wondering why that module wasn't taken over at that time with the abandoned modules → process.

Address Autocomplete has never released an official version, this is not the main reason for me to write a new module. But the configuration of the two modules is different. Address Autocomplete is configured once in the module, while Address Suggestion module is configured in each field. This difference is very big and cannot be merged.

That is very helpful information indeed! Please add it to the project page. Thank you.
