Realistically, this is the kind of restriction that's in place to impede the high-frequency & low-capability regime in the space of non-nation-state (or, historically e.g. the 70s, non-peer nation) threats.
That makes sense. However in today's ever expanding electronics-wonderland, I wonder if it matters anymore.
I think, post HK protests, it's going to be harder to order precursor parts from China. All sorts of jamming and drone tech is being used there by both sides. Hopefully we see restraint and mutual de-escalation and we don't see any use of energetics.
