Simply because the determination of power level switched from DC input 
to RF output, it having been established that power at the peak of the 
modulation envelope was what mattered.  Anything other than 400W CW 
would have required a licence in which power by mode was specified.  
Just think of the work load.  Every time a new mode emerged a power 
limit for it would need to be determined.

This would have been a complete administrative nightmare as well as a 
technological nonsense.  It had already been established that power at 
the peak of the modulation envelope was what mattered.

Thank goodness a clear thinker was there to see good sense prevail.
