Implement interface which permits accessing Proton Drive as network share
As a Linux user I’m using duplicity/deja-dup for my local backups. This backup application also supports several protocols to access remote locations, such as ftp/ftps, nfs, ssh, sftp.
In order to make use of Proton Drive storage in this context it would be necessary to access Proton Drive via some of these protocols which would be of great benefit since then incremental backups would be possible.
Currently I can only make a local snapshot backup and then transfer the generated files as a whole bunch which takes considerable transmission time.

I would have assumed that this was possible as well. One Drive and Google are already default options, why not Proton?

I was hoping this was something I'd be able to do already. I guess this is more or less online cold storage right now. Hoping this gets implemented!
