Yes, this question should be un-deleted.
It is answerable (and more easily now with the added links) and will no doubt be answered within 30 days if it is un-deleted.
Answers to this question might be highly relevant to answers to other related ASE questions such as Does FAR 91.155c apply to class E surface extensions? and Does an SVFR clearance extend to Echo surface extensions? and Which parts of class E airspace can an ultralight (part 103) fly in without prior ATC authorization? and What is the primary reason that the non-towered airports ACV, TVL, SGU, BIH, and SIT/PASI have E4 extensions to E2 airspace? .
If so, it is much better to have the content consolidated in a single answer where it can be linked to from other answers, rather than added in a duplicate fashion to multiple other answers.
The FAA's original intent during a specific rule-making action, which is still having significant effects on aviation in the US and is still generating relevant questions to ASE, is within the logical scope of ASE.
The question is not a duplicate of any ASE question and appropriate answers would not be duplicates of any ASE answers, because the question is not about any later (post-September 16 1993, the effective date of the "alphabet" airspace re-designation) rulings or other issuances from the FAA.
Likewise, answers to this question could not serve as complete self-contained answers to any of the other ASE questions noted above, or other similar questions, because factors other than the FAA's original intent also come into play when considering the current interpretation of regulations. Therefore the question is sufficiently distinct from any other ASE question to justify un-deletion.

PS-- as to why I am posting this q and a here-- from How does deleting work? What can cause a post to be deleted, and what does that actually mean? What are the criteria for deletion? :
If your post was deleted by high-reputation users or by the Community
user, it will require three undelete votes to be undeleted (more if
it's a question and it was popular) - politely asking for this on the
per-site meta may attract the necessary votes if you make a good case
for why the question should be restored
Question has now been un-deleted, thanks.
