Which changed to KeepassXC looking to support the standarization work to allow passkeys to be moved between user-controlled software products.

The complaint wasn't in allowing credentials to move (that is the point of the CXF and CXP work). The complaint was in having sensitive data in a plaintext file live long-term without any protections. That is also why one of Tim's early recommendations was to require encrypting the file via a passphrase.
