Yes even when I started in photography back in the 60's films emulsions were significantly softer during processing. FP3 and HP3 which I used at school (cheap ex-Government surpus) were softer than FP4 and HP4, which were again softer than the modern versions FP4+ and HP5+.
I knew that many German 35mm workers used Rodinal at 16?C or 18?C but I haven't come across that particular Agfa reference before, I think ironically I may have a copy of the book but then my German is non existant although I can tranlate a formula . What's important today is that the Agfa Rodinal from 1964 onwards has a higher pH and excess Hydroxide compared to the pre WWII version so the issues could be worse.
Part of the problem when discussing the issue of micro (surface) reticulation is most people with a good grasp, understanding and experience of processing should never come across it as a serious problem. However it is the reason why some photographers produce constitent high quality negative and prints while others using the same film/developer combinations can't even when the exposure & dev times are correct.
