Experience with answering option 252 with simple newline?

We're considering replying to DHCPINFORMs
with option 252 with a newline to induce
clients to stop asking.
Anyone doing this on a large scale, i.e.
while trying to serve all sorts of clients?
In theory, something could break.
What I anticipate doing (globally):

option msft-wpad code 252 = text;
if substring (option vendor-class-identifier, 0, 8) = "MSFT 5.0" {
	option msft-wpad "\n";
