Not sure what Messicks' reasoning is, but I know that it's not just the removed material that is of concern in reducing the integrity of the material, it's the longer-term affects of rust. And something like this can precipitate rust internally, where it won't be seen. But, yes, how much can this really be a concern is pretty hard to say. Keep in mind that everyone's environment differs: I have a friend in Nova Scotia who regularly reminds me of this through his battles with rust on mechanical things.
I'd wager that Kubota treats the ROPS after drilling, just as nearly all manufacturers do.
My decision to use U-bolts is that I'd be able to move the lights if I found that my initial thoughts as to where they were "best" mounted proved to be less than best. One can fill holes via welding but there's the issue of internal rusting. Not that my environment is all that conducive to rust (very minor compared to other places).
