 This is a follow-up to #56313.

 Following this ticket, seems that adding fetchpriority to module scripts
 gives no luck.

 **So any imported script has high priority, even when they should have low
 fetching prioritize.**\\

 I guess that should be a plus, to allow that choise / filter also for
 modules and importmaps, while actually loader_tag , script_add_data, not
 even replace  or HTML API seem having effect.

 I guess that giving a low priority hint, sparingly and with proper
 controls, can bring an improvement in overall performance.
