There is a lot of overlap between WiFi and Bluetooth & BLE such that you just have a Wireless chip that does both. In fact I think with Bluetooth 4 the file transfer profile just establishes an adhoc WiFi network. You don't have separate Bluetooth and WiFi chips anymore.
Furthering that, in the mobile space the Wireless capabilities are usually integrated into the mobile SoC. So you don't even have separate chips for CPU and Wireless.
About the only time you see a separate Wireless chip is when a new technology is emerging like 5G and it's usually only an external chip for a generation or two until it can be integrated into the SoC.
So, if you were to design your own Bluetooth chip today you would also be designing a WiFi chip and then you'd probably just roll all that into a SoC with a CPU. No small feat.

I was once at a big BT testing company and asked about it, and they had like one device that could do it (a crazy feature-packed HTC WinMo device I think). And then Bluetooth 4.0 added BLE, and it seems like there hasn't been much development of classic BT since then.
