except now you need two shells :-)

this feels like the arguments in the early 1990s around perl, and how
it's unfortunate that the two schools of minimalism ("one thing that's
usable for everything" vs "lots of things that each do less") both
call themselves "minimalism" despite being almost diametrically
opposed. (i personally call them perl minimalism and unix minimalism,
but "batteries included" might resonate more than "perl" these
days...)
