Filesystem not writable

Hello,

since the current update the plugin shows in the overview: “filesystem: not writeable”.
Before the update it was shown as writeable – but I have strict read / write permissions on my server, so indeed the plugin directory is not writeable by the user running php-fpm.
I just wonder if this is a problem for the functionality of the server, or if it’s just there regarding updates or anything else? I do these manually with wp-cli, so this is not a problem for me. Just wondering if core functionality of the plugin is affected.

Thanks and greetings
