Yes, with a JWM iso there would be no need to also post a .jwmrc separately.
As I explained elsewhere to Thierry, I do not have much technical knowledge. However, I do understand a little bit what you have been experiencing while configuring JWM. I did that a bit myself when starting to explore linux as an idea for making use of some older, spare computer hardware. (That idea also led me here to NuTyX.)
I look forward to seeing the iso with JWM when you have time to produce it.
