I strongly suspect that a number of the complicated AGC circuits evolved
because a simpler AGC circuit was poorly designed and/or subject to
problems like crosstalk from the BFO. Instead of solving the fundamental
problems, increasingly complex circuits are developed until one
accidentally works correctly, then the improvement is credited to the
complex circuit rather than its accidental relative immunity to the
results of poor fundamental design. This isn't of course universally
true, but it happens pretty often.

All too many software wannabees work this way too.
