Yes but CW (and FSK/RTTY) are dead according to the FCC and ARRL.
Now its all modes that require linear amplification over at
least 2.7 KHz. Better get used to it!

Of course if one sticks to CW this isn't necessary.

SDR based predistortion are most effective if the individual stages
are as clean as possible. That means 24/48V amplifiers for power
levels above 25 to 50 W and 60/100V devices for 500+W amplifiers.
The issue relates to voltage clipping and current saturation. No
amount of predistortion is going to clean up square waves.
