The problem isn't amplifier designers, it's the radio designers.
Check almost any "modern" solid state rig and you will find an
initial overshoot on the first CW character ... even without an
amplifier connection. The transceiver circuits have almost no
"standby" ALC bias so at the first CW "dit" the transmit circuits
are running wide open. The ALC attack time seems to be deliberately
"slow" ... probably to avoid acting like RF clipping for SSB.
