Request for new feature: discourage downloading to layer

[jan.cnops@…]

I often use layers of data (results of queries etc.) in which I make no uploadable changes, but do not want to add downloaded data. The "discourage uploading from" option is already quite useful for me, but "discourage downloading to" would also be useful: I know spend quite some time purging accidentally downloaded data from such files.

You can lock a layer, see #22047
