Based on personal observations, I'd say yes. When Campagnolo introduced their braze-on front derailleur, circa 1982, there were numerous cases of seat tube damage, with the fitting being ripped from the tube in severe cases. This caused a backlash against brazed-on front derailleurs. When Columbus addressed the problem by introducing the SLX/SPX tubes, the Europeans accepted the solution and used front derailleur braze-ons with SLX/SPX but were reluctant to use them on SL frames. Eventually they did come around but for a time in the mid-1980s, front derailleur braze-ons were relatively rare on European market SL frames. Their presence on any USA models seem to have been at the insistence of the importer.

Another example seems to have been pump pegs on the head tube. Many European brands reportedly included these reluctantly, again at the insistence of their importers.
