How does a document become part of the base specification (793 for
eg;-)? Does a document which clarfies some things left/out or corrects
errors like (1122 for eg;-) become part of the base specs?

My understanding is the strength of a proposal is determined by the
language used (SHOULD/MUST/MAY etc.,) and that covers everything
including guiding an implementor to implement the proposal or not. For
eg:- a TCP stack need not implement TCP secure mitigations at all but
MUST implement slow start for example. 

If someone determines (I assume they know what they are doing in most
instances ;-) that proposals recommended in a particular RFC is needed
either in part/full then they would put resources to get that
accomplished in their stack. Isn't the "standard" way ?

Or are you saying "base specfication" is something akin to what the
roadmap document is talking about under the section "basic
functionality"?

Confused,
