sunfishcode opened PR #4666 from stop-using-notcapable to main:

ENOTCAPABLE was an error code that is used as part of the rights
system, from CloudABI. There is a set of flags associated with each file
descriptor listing which operations can be performed with the file
descriptor, and if an attempt is made to perform an operation with a
file descriptor that isn't permitted by its rights flags, it fails with
ENOTCAPABLE.

WASI is removing the rights system. For example, WebAssembly/wasi-libc#294
removed support for translating ENOTCAPABLE into POSIX error codes, on
the assumption that engines should stop using it.

So as another step to migrating away from the rights system, remove uses
of the ENOTCAPABLE error.
