Having a bit of cold feet about this now.
I didn't realize that the default umask isn't 0 but 0o022, unless you configure it otherwise.

How about only removing the query version of Deno.umask? (i.e. keep Deno.umask(newMask: number): number and remove Deno.umask(): number. That also solves the broken permission issue.

Researched a little bit on other languages. Python and Golang has only setting APIs. Ruby has both. Node.js used to have both, but deprecated querying version recently after a similar discussion to our case.
