Not exactly.

I wasn't suggesting any change to `round'. I was suggesting changing
`integer?' to only return true for exact integers.

This means that the results of `round' would usually not return true
when passed to `integer?', but they could still be considered inexact

But anyway, there is enough opposition to the proposal that things are
unlikely to change, at least for now.
