Points to Romania for shooting it down, over the Black Sea but within their airspace.

But if they actually needed an F-16 to do the job (vs. that being a cover story, or good politics, or their least-revealing option)...yeah. They might want to invest in drone defenses with less-horrid cost asymmetries.
