[R] read.table(..., header == FALSE, colClasses = <vector with names attribute>)

I noticed that starting with R version 3.3.0 onward, this generates a
> txt <- c("a", "3.14")
> read.table(file = textConnection(txt), header = FALSE, colClasses
= c(x = "character", y = "numeric"))
the warning is "not all columns named in 'colClasses' exist" and I guess
the change was made in response to this?
Regardless, I am wondering whether this is desirable, that as a result
of the change, the code has become stricter about the presence of a
(formerly) harmless names attribute. Or am I missing something?
