Nerys Myk has it.
I was shocked in 1979 by the new look Klingons. It took me perhaps a week to get over it. I didn't need a "canon" explanation or to be told something was retconned. By the time I got the STTMP fotonovel, I didn't are.
I was nine years old.
For almost 25 years there was no explanation. People grumbled. People laughed. People theorized. No one said that there was a lack of respect for the fans.
Well...
