Implemented.

OpenSSH 8.8 disabled ssh-rsa by default. Until WinSCP 5.20 is released, add this to server's sshd_config to re-enable it:
PubkeyAcceptedAlgorithms +ssh-rsa

The problem manifests as "Server refused our key".

WinSCP 5.19.5 will log a reference to this bug, when an OpenSSH 8.8 (or newer) server refuses the key.
