[p4] p4 integ with "-i"...any harm?

Personally I would not turn on by default. I would look for the occasion
when it was demanded (by error message), and then investigate and seek to
understand what happened. One example, a new user might mistakenly add the
same file to 2 branches rather than adding and branching. I would like to
detect this and "educate" them and convince them of the error of their ways.

So I would turn off and keep an eye out for when it seems to be required.
You should find "hardly ever".
