[wix-devs] 5355 - util:RegistrySearch clears the variable when the key or value is not found

[Bob Arnson]

I also think it's an excellent proposal. I'm not sure to do in WixCop, other than issue a warning. The typical workaround in v3 was to author an "Exists" key for every other, so you could say "FooExists and FooVersion = v1.0" -- that would still work in most cases but could be simplified.

I'd like to get  https://github.com/wixtoolset/issues/issues/5355 designed since the proposal is technically a breaking change: "Rather than add a Default attribute, maybe the search should work like MSI, where a missing value doesn't overwrite the default." I think the proposal is good, unless someone else wants to do it differently?
