I don't think so. Some users may want to keep the figure between
blocks, and they can always clear the figure themselves when
necessary.

Thanks for your suggestion and I have added some arguments (e.g. :dpi)
in the updated patch. But rc_context doesn't work reliably with
multiple blocks in a session, i.e., the figure size may not change.
BTW, I have updated the patch to turn off the feature by default,
since it may break existing src blocks using `graphics'. WDYT? Thanks.
