I noticed on boot, WindowServer was getting an veil error:

With some digging I found out that the ConfigFile class was causing
trying to flush writes of default values, not present in the .ini
file back to disk on destruction of the object.
This sneaky behavior from ConfigFile seems to violate the public facing
semantics of the function (it's const). It also makes it very hard to reason
about the system with technologies like unveil where we are trying to
explicitly state what is exposed to apps, how those exposed items can be
used.
The functionality also doesn't seem to be all that useful, as we'll just
return the default value from the API's anyway.
This change removes the write back of default values.
