That idea is to set the global mail_plugins to contain the plugins you 
would want enabled in *all* places. If there is not a single such 
plugin, then indeed you can set the global mail_plugins to empty, but 
then you should still use $mail_plugins everywhere because then it would 
just work, should you ever add a plugin to the global list.

I don't see why you shouldn't add quota here, and zlib too in your case. 
If you don't use lda at all, it still won't hurt.

Finally, doveadm is sort of a "protocol" too and any protocol for which 
you did not specify its own "mail_plugins = ..." will use the global 
value itself.
So for example here you explicitly turned off all plugins for lda, 
overriding the global value. And doveadm will use the global value. So 
just take it all into consideration.
