In the same way that we have an alias rm -i for rm, how about vi being a
script that prints up a very abbreviated usage of vi that then executes vi.
The script can live on the install disk. The traditional wizard can exit
sysinst, rm the vi script and carry on as usual. First time users get the
basics of vi before being thrown into it (it isn't that hard, just that if
you have never seen it before, working out how to exit can be tricky!) When
the system is up, then all of pkgsrc becomes available. The only "bloat"
then is the number of bytes in the help message...

Just a thought,
