Yes - and this was back in the 1950's - many of the requests being approved, such as leaving the Royal Doors open throughout the Divine Liturgy.
Part of the problem here is that (as far as I can tell from the historical record) the European bishops WANTED a solution to the liturgical conflict, and asked Rome to provide one; there was never the same kind of desire in the diaspora, which was dealing with different issues. Furthermore, the circular letter from the Orientel Congregation did not order the bishops to use the new books; it seems to assume they will, and provides some guidelines (such as using only the new Slavonic books in seminaries).
By the way, the book you are reading, I think, is a translation of the Ordo Celebrationis, with notes and translation by Father Serge; I don't THINK he is ancient enough to have written the Ordo! And that same commentary does note, for example, the number of places where, in many places, it is traditional to follow different rubrics from those in the official books (for example, omitting the Royal Office at Matins, leaving the Royal Doors open throughout the Divine Liturgy, and distributing antidoron after the dismissal).
Yours in Christ,
