The archbishop is not asking for permission to have Mass. But since indoor Masses are prohibited (!) and Mass must be outdoors and limited to twelve (12) people only, no matter how large the available worship space outside is, and since the people wear masks and social distance, and since protests with unlimited, unmasked numbers are permitted without limit, he’s making a reasonable request after some months of successful outdoor Mass IN these limits to increase the participation.
Seems reasonable to me.
