I see your point, Ethan; the original purpose of the hack was using gnuplot as a web service, however, where the extra process overhead is significant.
Doesn't the fact we allow image size to be designated in pixels mean that we're superficially concerned with image processing? Otherwise, we'd pick a default size and force people to do:
set output '| convert -resize 600x800 png:-...

The attached patch lets you 'set isosamples 1' and falls back on the
single-curve.
set isosamples 1
plot [-1:1] '+' using 1:(sin($1)):(rand(0)/10.):(rand(0)/10.) \
with vectors
or:
set isosamples 30
plot [-1:1][-1:1] '+' using...

This patch adds a crop option for pngcairo à la gd.trm.
For example:
set term pngcairo crop
plot x.

The following works, as long as you specify a y-range:
plot [-8:8][-1:1] '+' using ($1):(sin($1)):(cos($1)):(sin($1)) \
with vectors

Vector plots (e.g. direction and gradient fields) require two dimensions of data; the patch detects whether df_current_plot->plot_style == VECTOR and produces two dimensions of data accordingly.
Example:
set isosamples 20
set samples 20
l = 0.05
f(t,y) = 2*y + 4 - t
g(c,x) = -7/4. + 1/2.*x + c*exp(2*x)
plot [0:2][-4:0] '+' using 1:2:(l):(l*f($1,$2)) \
with vectors title "dy/dt -...
