Taking into an account that we already have an ability NOT include data 
from some tables into backup/restore process I do not agree with you 
here :) Well - not 5 lines change but certainly very far from 
"fundamental changes".

Yes.

This can be better answered by an author of a ticket :)
I can imagine for example a need to try a number of statistics queries 
on some predefined set of tables (including SQL debugging needs). One 
may try one, another, etc forms of SQL to get desired results. Later 
appropriate indices may be added to optimize query which provides needed 
result. In order not to overload production server it's good idea to 
work with database copy on another box. But making a copy of all TBytes 
of initial DB is not needed - we need a limited set of tables. In that 
case mentioned improvement can help making such DB backup faster (yes, 
it will have broken FKs, but for mentioned purporse it doesn't matter).
