The performance reason that may have been important in 1977
is probably not relevant any longer.

But running it in P0 instead of P1 will change some
things.

It will require external programs to be run in another
process instead of same process.

And that has an impact on many things like
symbols, logicals, default dir etc..

I am not saying that it is a bad change.

I am just saying that it is a major change.
