Did you really hear that many complaints that it's worth to take care
of this?  

If we have a minor release of 4.1 every two month that means a time of
less than two month where a user first updates to 4.0.3 and then to
4.1.0. I doubt that users update in that way so often that we have to
take care of that.

On the other hand, I know of users that have several branches
installed to test both old and new compilers and those might get hit
by this,
