No. That possibility is already in XSL 1.0.
Extension functions may cause side effects.

xsl:script only offers a standard mechanism for binding extension
function names to implementations, it doesn't change what an extension
function can do.

I thought it did (Mike Kay's book certainly does) but I just had a quick
look and didn't spot anything explicit. But either way this is an issue
already in XSL 1.0 not with xsl:script.
