NO WE WON'T. For a start, Class E does not require it. That is the whole point of E: VFR do their own thing with no consideration of others! For goodness sake. Martha and John King rammed that down our throats here 15 years ago on the "hard sell" tour. Now IF ATC can see a VFR (no radar or ADS-B coverage down low), then they MAY tell us about it but are not obliged to: AIP-"IFR receive traffic information on VFR flights as far as is practicable."

That's only because Dick knew he would get nowhere without it (given that heavy metal operations through unknown VFR airspace, especially terminal, was and still is sheer lunacy). TCAS is NOT a method of mitigating collisions; it is a last-ditch safety tool like GPWS and the STCA.
