That depends upon the compiler recognizing it as a "confirming
representation clause", ie a special case that does not change
anything. I would expect all of them do now; certainly the ones I
know do.
Still, I think it is bad form to put them in when no longer required,
just in case your compiler does not recognize that nothing is changed.
The resulting code generated can be really ugly (in terms of
performance).
