Yes, it has this ominous undertone, like it's bad for X to be that way somehow. :D
For some reason, I thought Light didn't use the number system like Wily did.... now that I'm thinking about it though, I'm remembering that Blues and Rock both have numbers- but they were also both handled by Wily, so. It seems more in character for Wily to slap a number on things than Light to do so... Ignoring that, does X then have a DRN number? :D
I read 'expandability' as 'expendability' too at first glance...
I remember once you mentioned that the official sourcebooks sort of describe X and Zero like expensive cars- I can see where that impression comes from after reading this. It's like a sales brochure. :D
