Is emacs?
It seems to me that both religions are not 'standard' anymore. I tend to see pico, nano, joe etc. - occasionally vi (but not vim).
I knew a guy who actually did this - he worked for a company that maintained process control systems for "serious" customers (steel mills, nuclear power stations). One steel plant had some ancient mainframe controlling things and it originally booted from paper tape that had long since worn out in the eons since it was installed and been replaced with a sturdy leather belt.
He had to patch the boot code - so hence had to resort to a handdrill to drill some new holes in the leather belt.
Why frig around with emacs, pico, nano etc when vi is always there and is the same?

If you want to use vim for development, use vim. But "it's the default" is simply an untrue statement. Vim (-full) is no more "the default" than Emacs. Both need to be manually installed on nearly every operating system.(OpenBSD ships with both nvi and mg, FWIW.)
