Is this a preparation for LINQ-like functionality?
Delphi compatibility. But as the example shows you could use it for
LINQ-like functionality as well.

With false and true being integer, how could it be used in an
boolean-expression-expected context? e.g. if, while and until condition?
Anyway, AFAIK classically Boolean is declared as enum:
type Boolean = (False,True);
Delphi compatibility (or as is written for that entry: compatibility to
other Pascal compilers in general). This won't have any negative impact
on logical expressions. Also keep in mind that comparisons with "= True"
could lead to wrong results anyway as "True" for Boolean and friends is
"1" while "True" for ByteBool and friends is any non-zero value.
