Yes, you could make thicker tubes out of cro-mo but they might be more expensive. So the real answer is when you stiffer and lower cost. Of course there are some really great bikes made of hi-ten and similar.
I really don't know what my UO8 is made of. Peugeot didn't use any recognizable frame sticker other than in oxydible or something. I've always supposed it was like hi-ten. Except for the slightly higher weight it rides very nicely. So I must conclude it goes up to hi-eleven.
