Jokes aside, people should learn to not treat IRCC as a responsible governmental body of a developed country because they're not. Since this whole process is just as shooting an arrow into darkness and only learning whether it was a hit or miss in at least 12 months, people should act not only diligently with their submission, but paranoid. Paranoia saves you in this mindfuck of a process where IRCC won't respond to ANY of your correspondences so forget about webforms. Think about all the 0.000001% chance situations that could occur in one of the 10000000 parallel universes and prepare your documents accordingly.
