Hm, right, we're not talking Chrome or FF here ;)

Lord! What a boring UA. Every last one ends in .0; (dot, zero, semicolon) leading to single space* and more stuff.
I limited my search to requests that got through with a 200. So if there are any other numbering formats, they're strictly in Bad-Robot-Land and need not concern us. There were definitely non-zero versions of 5-- the last Mac version was 5.23, but I only use it to test my own lockouts ;) If you ever meet a 4.01 it will be part of a costume worn by unfashionable Russian robots.
My own [1-4]\. was for unconditional denial, so the fewer details the better. It's only with 5 and 6 that I make judgment calls, and that's getting into YMMV territory. I can probably dump the 5; I think even Iqaluit has finally upgraded the last of theirs to 7 or 8.
* Except the plainclothes MSNbot, which likes double spaces.
