Yes, that would have been a much simpler rule. In fact, that's the way it
was for a while. But it caused problems, both in terms of backwards
compatibility and in terms of what users found natural, so we changed it.
The difficulties related to the strong expectation that strings produced by
adjacent xsl:text/xsl:value-of instructions would be concatenated directly.
