It would be a lot less of an argument then, and I would be willing to bet that the language would evolve into a far less web-centric area. But in part because of this, if you actually try to do anything outside the web (I have) in PHP, it's not all that pleasant.
Also on the PI tag issue, I would rather keep my PI tags limited to the view or template. it leads to a lot better clarity. and your object classes are no longer technically SGML fragments ;-) This has some nasty side effects if you have a leading space before your opening PI tag and you aren't outputting SGML....
Oh, as a side note, by 'escape from the web' I guess what I really mean is 'escape from SGML-world.' There's a lot of the web that's not SGML-driven and there's a lot of the non-web that is (XML, DocBook SGML, etc).
Bottom line, PHP is a decent tool for working with SGML but it is highly specialized for this. You run into weird things working in SGML mode but not in non-SGML output with things like leading spaces before opening PI tags if you move out of that. Since this is lexically part of the language, I just don't see it changing.
