GitHub CodeQL reports for overly permissive file permissions

CodeQL has a Python rule with ID py/overly-permissive-file which flags several chmod/open calls in the node-gyp Python code. I would like to confirm that these operations are intentionally more permissive and safe to suppress.

Flagged locations

File	Line	Code	CodeQL concern
gyp/pylib/gyp/common.py	561	os.chmod(tool_path, 0o755)	World readable
gyp/pylib/gyp/flock_tool.py	43	os.open(lockfile, ..., 0o666)	World readable/writable
gyp/pylib/gyp/mac_tool.py	250	os.open(lockfile, ..., 0o666)	World readable/writable

• 0o755 on common.py:561 is set because you are unsure whether all build processes are run with the same user
• 0o666 on lock files in flock_tool.py and mac_tool.py is intentional, with umask expected to restrict actual permissions

Could you confirm these permissions are intentional and by design?
