FLL feeder final was combined together. ROMEO was working Aircraft X inbound from the east for the 10L ILS final. Several controllers saw a 4;500 feet VFR [Aircraft Y] inbound from the north; descending southbound for the OPF/HWO area; and it was tagged as ''TFC'' acquiring the callsign via ADSB. Aircraft X was given an expeditious descent to get under the VFR as the Arrival Controller had numerous inbounds to both FLL parallel runways and it seemed this was the easiest way to de-conflict Aircraft X and Aircraft Y and go to immediately fix the other many aircraft who were also in conflict. Aircraft X was then also turned sharply in the descent in an attempt to join the final without crossing the projected path of the traffic; and miss a Caravan inbound for the airport too. Aircraft Y continued through the ILS approaches just west of PIONN; which has a crossing altitude of 025 and even turned back to the south and west to both miss the Bravo; but clearly also miss aircraft it saw out its window; creating even more problems for the ROMEO controller. The fact that this is allowed to happen and create unmitigated risk in the NAS is [absurd]. The traffic volume and complexity were already high; however had this event occurred during busier times of day; it would have been substantially more dangerous. FLL needs a bigger Class C airspace or a Class B! FLL airport is the 19th busiest airport in the USA; and one of the top 3 fastest growing; averaging 8% growth each of the last 5 years. FLL has a basic Class C airspace surrounding it that is beyond out of date and unable to aid in the safety of its aircraft on the finals. Planes inbound to each of their parallel runways are not offered any sort of protection until within 5 miles of the field; which allows several dozen VFRs each day to climb; descend; and transition across each final; without ATC advisories creating a very dangerous; unsafe; and hazardous situation in the skies above; not unlike San Diego in 1978. The FLL Class C is inadequate; and out of date; and needs a major airspace change around it; whether a bigger Charlie; or a full blown Class B before it's too late; just like [an accident in 1978] where people had to die before airspace changes happened.
MIA TRACON Controller reported vectoring several aircraft conducting instrument approaches off course to avoid a VFR aircraft they were not in communication with.
