Can you point me to the rule disallowing arbitrary nesting? I'm not aware of a rule existing in either direction, besides vague guidelines to write clearly. Also, which example is 1 level of nesting? I think "That's the woman the house Jack built fell on." is 2 levels nesting, and I frequently hear constructs like that – in speaking. I agree it's rarer in writing though. For example: What server is that? That's the server the consultant Jack brought in set up. I'd never write that, because it's confusing. But I will naturally say things like that, without any problem in clarity, because you have more granular control over grouping and pausing, etc. If I said a sentence like that, you might hear it more as "That's the server the-consultant-Jack-brought-in set up." Anyway, sorry if I misread your tone. It just came across very much as "I know what's right, and you're wrong." That might have been me projecting though. :)
