For another anecdote, Galaxy Nexus also supported BT 4.0 BLE with its Broadcom chip, but Google decided it wont enable it for 4.3 release. When I've found that out, it pissed me off immensely, so I found a solution how to enable the support and posted it as a flashable .zip on xda [1]. Same was also for N7 2012 and N10. After flashing BLE worked just fine.
Google doesn't care for its old devices, nor did it cared when it shipped, Nexus line was always awesome hardware, but not fully utilized by software, which is sad from an engineers point.
