I just wanted to play around with guetzli and when I tried to compress some images it told me that in order to go lower than --quality 84 I need to rewrite the source code.

Guetzli should be called with quality >= 84, otherwise the
output will have noticeable artifacts. If you want to
proceed anyway, please edit the source code.

Wouldn't be a short yes-or-no-prompt and a flag that suppresses said warning be much better?

Something along the lines of:

Guetzli should be called with quality >= 84, otherwise the
output will have noticeable artifacts. Do you want to
proceed anyway? [yes / no]

and some flag, probably -f, to skip the prompt.

What do you think?
