Will Google Analytics Importer still work after March 31st 2023?

When we analyzed a problem message from the importer plugin, we were also given this link:

Warning: The Google Sign-In JavaScript platform library for Web is set to be deprecated after March 31, 2023. The solutions in this guide are based on this library and therefore also deprecated.

Will the Plugin still work and help migrating companies from Google Analytics to Matomo? Or does it need to have an update? Is that currently planned?
