I _expect_ to have to type TAB when deleting electric characters.

Really, the only actually valid argument so far is Stefan's of typing

end M-x newline-and-indent RET

when in pascal and on

   a := 7.0
  ^

since it is

   end a:= 7.0

but

end
a := 7.0

except, of course, that it is actually

end;
a := 7.0

after all even in Pascal.  And pressing TAB on

   end;a := 7.0

still will do the right thing.  So I don't really think the "inserting
newline will actually cause a different indentation for the line above"
case is relevant enough to fall over backwards for it.
