Not entirely sure if I understand what is meant here. The foundation of any building (the opening bid identifying into which category the hand falls) needs to be layed first before the walls can be added (the continuation bidding in the auction) before the roof can be added (the final contract).
The foundation of any building is probably the most important part. A poorly constructed foundation will lead to the premature collapse of the entire building (the final contract failing).
For example, and related to this thread, Meckwell played Multi for many years, and now do not.
Having, or not having Multi, by itself, has made almost no impact on Meckwell success.
Deciding which hands to open a weak two in a major, with Multi when available, or 2

♠ when not playing Multi, has had an impact on Meckwell success.
Having a response structure, to whatever opens a weak two in major, that can find out opener's hand type, and that adapts to seat and vulnerability, has had an impact on Meckwell success.
Thus a success factor has not been Multi vs. not (opening bid framework question), but how to handle and when to use a weak two in the majors.
