Why not update sed to create the backup file only if the suffix is given to -i, like gnu sed does.

Wth is wrong with:
data=$( sed -e '...' somefile ) &&
echo "$data" > somefile
or
set -e
data=...
echo "$data" > ...
or
exec 3<<EOF
$( ... )
EOF
cat > ... <&3
or
(I digress)
Infinite variations, but the gist is that sponge looks to be trying to help sh(1)/similar when help is unneeded.
Why buffer data into memory via fork-exec-pipe to sponge when you can buffer to native namespace without pipe to sponge?
Am I missing something? Why do we need sponge(1)?
