It's true that the semantics are the same, and it would probably make
sense to do some optimizations on typed constants that aren't ever
written to(the FPC rtl "abuses" the typed constant variable property in
the heap manager code, for example)
I wouldnˈt consider this an abuse as type constants were intended to be
"static local variables" when they were introduce.
E.g.
procedure IncCount;
const
count: Integer = 0;
begin
Inc(count);
end;
The value of "count" will increase throughout the run, but it won't be
visible to other functions/procedures outside this routine (this goes
back to the time when Pascal had no units to introduce private variables).
