Agreed. The TL07x-H need a new part number.
There's already the TL07x TL08x and TL06x series. Why not create a TL05x or TL09x for this new CMOS replacement for JFET input op-amps?
Also, Texas Instruments has the Excalibur line of high-end audio op-amps. These are the TLE206x TLE207x and TLE208x families with JFET inputs. Not only are these great chips used in many commercial products, but they show how to rename the TL06x/TL07x/TL08x when designing new technology that's in the same vein.
p.s. I wonder if the -bur in Excalibur is a nod to (the defunct) Burr Brown.
