From the link Elden1971 provided, this is what I would hope would happen with younger generations in the Local Churches:
http://www.plymouthbrethren.org/article/5144
"Brethren beloved and longed-for, against whom there was no charge of wickedness or evil teaching, found themselves in opposite camps and as the years have gone on there has been very little change on the part of the older generation.
It is noticeable, however, that the younger believers of all the different fellowships are becoming more and more restive about being whipped into party lines and all are yearning for a broader and more Scriptural fellowship— a return to the first principles of the Brethren which we have seen have been so largely given up."
