[pstricks] Can pstricks skip issuing transparency stuff when they are unnecessary?

Dear Herbert and Rolf,
dear PStricks maintainers,
Let's construct mwe.tex containing
\documentclass{article} \usepackage{pstricks} \begin{document} test \end{document}
and run
latex mwe && dvipdf mwe
or
latex mwe && dvips mwe && ps2pdf mwe.ps
Then we get
%%%% WARNING: Transparency operations ignored - need to use -dALLOWPSTRANSPARENCY
on a tty. Could pstricks be a bit more economical and not issue the transparency stuff by default (or, equivalently, issue it only opacity and the like is really used in the user's sources)?

Thank you in advance,
