We can't do that here because '' would suppress interpolation of the
variable's value, which is sort of the point.
AFAIK, the locution "$foo" is safe regardless of what is in $foo,
as long as only one pass of shell evaluation is involved. The shell
will treat the value of $foo as one not-further-interpreted command
argument.
