I think because few proponents actually think through the impact
on end user machines. There are more constituencies to Debian than just
embedded users, and people write shell scritps on their own, and use
it as cron jobs, helper functions (I use a couple to handle mailto:

since there are more of them, and embedded systems end users, who can
definitely switch the link themselves.
