Classic and LE are completely different protocols, from physical layer and up. It must be that it doesn't make a lot of sense for manufacturers to invest substantial effort in it.

Which makes sense when you know it started life[1] as a separate protocol called Wibree by Nokia, which was specifically designed[2] to be usable by Bluetooth RF gear:

A major tenet of their design was that “it can be deployed with minor effort into devices already having Bluetooth, e.g. cellphones” with the added requirement that a “common RF section with Bluetooth must be possible”.
