Because it's completely unnecessary. But you don't seem to understand

But there are other reasons for delivering images from databases. There
are no good reasons for parsing every file as PHP.

No, you're just trying to change the topic. Your current argument isn't
succeeding, so you're desperately trying to find an argument you can

Oh, so now it's not part of the discussion? Make up your mind. Or is
it part of the discussion when you want to bring up a point, but not

You really need to understand parsers more before you make such claims.
Searching for <?php or <!--$foo are not the only things parsers must do.
